So let us step into this one, one hour classroom of New Math that
teaches the Calculus, the fundamentals of Calculus in that one hour.
In New Math we see the Calculus as just a refined form of trigonometry
and as coming out of trigonometry. In New Math we realize that the
fundamental feature of Calculus is that we have an
"angle" involved. Whether we are doing derivatives or doing integrals,
we are hunting for an angle that is represented by the points of the
graph.
I find ascii art painful to do, so I want to use them
many times to eke out their pain they caused me.
Here we draw any function on the blackboard and call it function "a"
"a"
| /

| /
|/______________
Call it the graph of function "a".
Now there exists two new functions call them "d"
and "i"
| "i" "a"
| / /
| / /
| / / ______ "d"
| / /
|__________________
Now "a" is the original function and every point on "a" has a angle
associated with that point so that the angle is a slope at that point,
a rate of change of that point. And this angle for that point and all
the other points of "a" constitute a second new function which we call
the derivative of "a" and I graphed it as "d".
Now with "a" every point on "a" has another angle associated with it
such that this angle causes the picket fences around all the points of
"a" have no excess or deficiency in area. And every point of "a"
has a unique angle to make sure the picket fences under the curve of
"a" are all exact picket fences with no excess or deficiency in area
and the collection of those angles forms another new function called
"i".
So in summary, Calculus is the handing up of a curve on a graph and
then the Calculus seeks a angle curve that is the derivative and
another angle curve that is the integral.
And here is a number example of what is probably the easiest function
for "a" to learn Calculus. It is the function F(x) = x and is a
45degree line that bisects the first quadrant. It has a name-- the
identity function.
And it creates two new functions of "d" and "i", the derivative
function of "d" is 1 of F(x) = 1, and the integral function "i" is
1/2x^2 of F(x) = 1/2 x^2.
Here we quickly learn the rule of taking the exponent of identity
function as 1 and so the derivative of x is 1
and then asking what function can I play that trick on to yield the x
as derivative? The answer is 1/2 x^2 because when you do 2* (1/2) you
have 1 and when you do x^(2-1) you have x. So in this one hour lecture
we teach what Calculus basically is--- angle hunting
And we teach how to find a derivative and integral of the identity
function which applies to many other functions. And we teach that the
derivative is inverse to integral because they both are using the same
rule.
In New Math we recognize that the concept of Limit has no place in
Calculus and about the only place it does have use is in series. To
use Limit concept in Calculus would be as ridiculous as the upcoming
London Olympics where the judges are mathematicians who go out and
measure a running race not with a timer but with a limit concept. As
ridiculous as measuring a speed swim not by a clock timer but with a
limit calculations.
Ascii art maybe painful to draw, but is nowhere as painful as to see
millions of students heading off to school and having to be
brainwashed with the worthless Limit concept in Calculus.
In New Math, Calculus is all about angles formed because numbers when
plotted as graphs produce angles naturally. Of course, when we see the
trig functions of sine or cosine or tangent, we often see only those
numbers on the graph paper and ignore the fact that every number on
the graph paper also represents angles in trigonometry.
In New Math, we can indulge with limits but their use is very
restricted, and if we did want to use them, we can more easily just go
to the zones of algebraic completeness of the Infinity number 10^603.
End of one hour lecture.
Now admittedly that lecture would be for first year college, but if I
deleted much of the talk about limits, it would do nicely in a High
School class.
The main idea is that Calculus is a offshoot of a trigonometry
classroom. Trig is about angles and circles. Calculus is about angles
and functions. Both trig and calculus are plotted on graphs, which
means, both are basically angle hunting.
What this textbook is wanting to do is to expose the limit as a
concept that was a fake concept applied to a subject that never needed
it. We do not need to carry around and use coats in the summertime.
Calculus never needed the limit. And the only reason the limit was
"thought to be important in Calculus" was because mathematicians never
defined infinity precisely, so they threw into Calculus the limit,
thinking it would cover up any talk about infinity.
Now when I went to school, the limit was taught in first year college,
not high-school, and I hope that practice remains true, because I hate
to see young pre-college students brainwashed before they even reach
college. To step foot on college campus and already brainwashed with
limit.

Only in the UK. In the US, it's abbreviated to "math".
Of course, what AP is doing is neither.
> Do you study home economic?
That would be abbreviated to "home ec" (not "ecs") in the US.
You must life in the old British Empire to call mathematics Maths.
Lying bastard. Boring lying bastard. <yawn>
