In this set of printable worksheets for 3rd grade, 4th grade, and 5th grade kids are required to identify whether the pair of lines is parallel or perpendicular from the objects they are using in day-to-day life.

Classifying the relationship that exists between two lines can help us understand a great deal about a system. If they are perfect straight, in relation to one another, this can help you to better understand the angles that forms when a transversal line crosses both of them. When two lines are a fixed distance apart from each other infinitely this relationship is described a parallel. Line that are in this form of relationship will never cross each other. When a line crosses another line at exactly 90 degrees, we describe those lines as being perpendicular. This selection of worksheets and lessons will help students learn how to identify these relationships. In future topics we will learn how to use the information provided by these relationships to better understand an entire planar system.

We see lines going in different directions, don't we? Sometimes they're going upwards, downwards, straight, sideways, or at an angle. Sometimes they meet or cross each other. The purpose of this is to take some time to define the vocabulary of how these lines interact. Let's find out!

Parallel lines - Have you seen how the railway tracks run on the ground? They are quite apart from each other and seem like they never meet. Well, that's exactly what parallel means. A set of lines that are on the same distance with each other and don't intersect are called parallel. An easy example to understand better is the "=" sign.

Perpendicular lines - You must have seen how a pizza is sliced, right? They are cut from the middle, and sideways. Notice how at the center, they meet? The common endpoint of these lines is known as an angle.

As you advance forward with geometry and math in general, these relationships will be given or previously stated to you in the problems that you are responsible for. If you can identify that these types of relations exist, it tells you a great deal system that you are evaluating. If you find a parallel series and transversal cutting through both lines, the angles that are formed are quite easy to determine as long as you are given a single angle. It is almost amazing how much the tell about a series that exist in this manner. When you discover a perpendicular, it can help you solve linear equations not to mention simple angle measures. While this may just seem like simple math to you, as you start to build anything with your hands you will learn the weight of these connections that exist. I learned this firsthand when building a simple ten by ten deck off of my house. Geometry of angles is powerful form of math that can be used as a tool to create some awesome structures, I explain this while sitting on my deck. Which was fashioned thanks to geometry!

You will cover a wide variety of materials during classtime, so your constant attendance is important. To help you in organizing your study materials, the list below gives an overview of the basic concepts covered during a given lecture period. Exam 1 contentLecture 1 (Jan 22): Welcome to Math 116!We spent the first part of class today discussing some logistics for the course, including taking a look at the syllabus. At the very end of class we introduced the area problem.

We did more problems involving integration by parts, including some that required us to "get creative" using some algebra facts. At the end of class, I handed out this work sheet (solutions) and this worksheet (solutions) which give us more practice with these skills.

In today's class we explored a somewhat unexpected application of integration: the computation of volumes. The idea was that one could approximate the volume of a solid by taking small "cross sectional slices" of the volume, and then approximating the volume of each "slice" as the product of the cross-sectional area of the slice times its thickness. Following this procedure through increasingly small slices, we were able to argue that the volume of the solid can be thought of as the definite integral of cross sectional area. We used this method to compute the volume of a cone. We used this as a starting point for thinking about how we compute the volume generated by revolving a $2$-dimensional region around an axis of rotation, particularly in the case where one has "sliced" the region in a direction perpendicular to the axis of rotation.

Building on the ideas from last class, we were able to create even more high degree tangent polynomials. In fact, if $n$ is any positive integer, we were able to create a degree $n$ tangent polynomial to $y=f(x)$ at the point $(x_0,f(x_0))$; we called this the degree $n$ Taylor polynomial, and we computed it as$$\beginalign*T_n(x) &= f(x_0)+f'(x_0)(x-x_0)+\fracf''(x_0)2(x-x_0)^2 + \cdots + \fracf^(n)(x_0)n!(x-x_0)^n \\&= \sum_i=0^n \fracf^(i)(x_0)i!(x-x_0)^i.\endalign*$$We saw how we can use a high degree Taylor polynomial to give estimates for even the most complicated functions, at least assuming the point we're estimating is close to the point of tangency. (If you want to play around with the tool we used in class, you can use this Geogebra applet that lets you input a function, a point of tangency, and a degree for the Taylor polynomial.)We also saw that there's some hope that these Taylor polynomials might give extremely accurate approximations, even (in some cases) for points that are quite far from the point of tangency. This motivated a handful of important questions, like

how can we know how far away from the point of tangency we can get in order for these high degree Taylor polynomials to give good approximations for the function, and
can create something like the limit of these tangent polynomials, and (to hybridize these two questions)
is it possible that if we took the limit of these tangent polynomials, they would actually be equal to the function itself?

To end the class, we started to introduce the first idea we need in order to answer these last few questions. To do this, we introduced the notion of a sequence. Intuitively, a sequence is just an infinite, ordered list of numbers. We saw several examples of sequences.Exam 3 contentLecture 24 (Mar 25): Limits of sequencesIn today's class we introduced the notion of the limit of a sequence, both in terms of its intuition as well as the technical definition itself. We tried both of these ideas out in practice on a few sequences. We stated the technical definition, and started to think about why this technical definition captures the intuitive idea that we have for a limit. We saw how to start verifying that the technical definition holds in the case of a particular sequence.

For the first half of class today, we discussed some of the relevant topics for the second midterm. Afterwards, we continued our discussion of the technical definition of the limit of a sequence, and thought about how to implement the relevant ideas in specific settings.

For the last few class periods we have been thinking about the technical definition for the limit of a sequence. While this definition is important (since it makes precise what we mean when we say "limit"), it has some obvious drawbacks. For one, the definition doesn't tell us how to find a limit; it just gives us a mechanism for verifying whether or not a given number is the limit of a sequence. Second, the definition is quite cumbersome to use.For these reasons, we'd like to develop some theorems that give us better insight into how to determine the limit of a sequence, and which make computing limits easier. We gave two main answer to this question in the form of the "piggyback theorem" and the "kangaroo pouch" theorem. The first result of these tells us how to relate the limit of a sequence to the limit of a function related to that sequence; this is important because we already have a lot of tools for evaluating limits of functions (e.g., l'Hopital's rule). The second result gives us a way to evaluate limits of sequences that are built by taking some other sequence and plugging it into a function

Last time we saw that the geometric series theorem is a very powerful --- in fact, the definitive --- tool for analyzing series that happen to be geometric. But what if our series isn't geometric? Unfortunately, outside of telescoping series, the reality is that most series are enormously difficult to calculate precisely. Instead, one is often forced to be content with a much more coarse description of a series behavior. Instead of determining the value to which a series converges, we instead simply ask whether we can determine whether it converges or not. Though seemingly innocuous, this is already a fairly difficult question to resolve, and there are lots and lots of mathematical tools that have been developed to answer this question. Today we focus on two of those tools.The first of them is the divergence test. We saw that if a series converges, then this means that the partial sums must approach some constant $L$. But since the difference of two consecutive partial sums yields the corresponding term of the sequence (or, more precisely, since $s_n-s_n-1=a_n$), this tells us that if a sum $\sum a_n$ converges, then $\lim_n\to\inftya_n = 0$. Phrased a different way, this says that if the terms of a series fail to converge to $0$, then we know that the series $\sum a_n$ itself must diverge. The second test we discussed allows us (in certain situations) to relate the convergence of divergence of a series to the convergence or divergence of a certain improper integral. This result is called the integral test (but later we redubbed it the Linda and Heather test...at least for people who are willing to have silly names for theorems). Unfortunately, to apply this test we need to check a lot of conditions; on the plus side, if we can verify the appropriate conditions, this gives us a way to use our knowledge about integrals to answer questions about (much harder to understand) series.
