I love the way of representation of IGNOU books specially maths book, for these study material, I leave my degree college and join IGNOU for these, in HPU (Hachal.P university) there is only craming of facts. And at that time IGNOU books are just like , a thirsty man in desert, accidentally found Oasis. For me, I love the way of representation of concept, I read all blocks 1-5 BMTC 131. But I don't found any confusion while reading these books, these books are designed in such a way , that the IGNOU provide the key to me and I have to opened the door of knowledge. In first book I found some problems, if possible is there any video lectures. If yes then plz send the link.... And all over , I love the books.

Our material is not like market guide, where you have results and
examples without any motivation.  There is a lot of discussion going
on to motivate
the concepts and results.  We have tried to build in the teacher into
the material.
You are used to books that are taught by teachers in the class and teachers tell
many things that are not in the textbook.  So, you may find the
writing style a bit
strange in the beginning.  You will get used to it.
You may be able to understand the structure of our material if you see
this videos;
https://youtu.be/d0uVLSacIzA
https://youtu.be/8Ui2mpPDP7E
Our objectives are to help you formulate questions. We have provided a
large margin
so that you can make notes.
Here are some reference books that introduce you to the language of Mathematics:

Here are some videos on Mathematical reasoning:

Thia is becoming so frustrating cuz i see lectures on youtube and those doesn't match the books, yeah i understand sequence and all may differ, sub headings of the book is not friendly, i feel like i am reading from in between whenever i read. I don't get the author, but this is not the case with another subject be it physics, chemistry. Please suggest me how can i cope up, cuz i am an average child want to know the mysteries of mathematics, i would love to get all the lessons in my head, but i fall short, eveytime i attempt to persuade myself to read it once again, but i hardly get the concept. This is huge i never faced this earlier, i passed my intermediate from CISCE board, please tell me where am i failing. Help.

The answers are not different. All the powers of cos x are even in the answer for E5) in 105. Eliminate cos x using cos^2 x = 1-sin^2x. You will get the same answer.

Is heavily confusing specially in example 4....... And my one equation is that in integration is there is possibility if we try 2 different methods to solve particular question the face of answer is something different Are there any probability that the both answers are correct ....... And my final question is that please please please please please please please please please please see block 5 (page 47 example 8 and its second part ) and ( page 105 E5 first part )both question are same and apply integration in both questions. But your answers are different plz guide me about this question.

Please focus on my last question

[Devesh Rana]

Thanks a lot. .... respectfully What about my other questions. Menans facing difficulty in some chapter as I asked in previous mail. In chapter 2d geometry, relations, and polynomial. As I asked some questions. ... And also in application of integration the way of finding f1(x) and f2(x) is something different as we studied in 12 NCERT ... So I face problem in question page 133 area of straphoid.

[BSCG programme Mathematics]

Please see the enclosed PDF. What you studied in 12th NCERT may be
enough of solving
problems in 12th NCERT, but they may be difficult to use here. So,
you need to learn new methods.
Once you draw the figure for which you want to find the area, the part
at the `Top' is taken as f1(x)
and the part at the `bottom' is taken as f2(x).
If you find this difficult to understand, go to the web resources
section in BSC-MATHS and refer to
any of the books and see if you can find a method that you find easier
to understand.
https://sites.google.com/ignou.ac.in/bscgmath/first-semester/bmtc-131/web-resources-bmtc-131
As long as the method is correct and you have used it correctly, the
answer will be the same.
(Did you see E5) in page 51 of Block 5 and its solution?)
