Sir,

I thank you from the bottom of my heart for putting all these important formulas on your site. I really appreciate the fact that you are trying to guide the students in anyway possible. It would be very kind of you if you can give me a little advice. Our CBSE results were declared yesterday and I got compartment in maths 🙁 . I just want to score some decent marks or at-least pass in maths during the compartment exam that’s just 1 month away. I’m good in relation/function, matrices, vectors, probability (Bayes’s theorem)& 3-D. Frankly I failed in maths because I didn’t practice enough (the whole calculus part, LPP & area bounded). I’m gonna pursue English honors & so I didn’t put much thought into math. I now sincerely regret it. I would just like to ask you if I practice all the formulas in this page & follow the NCERT sols., will I be able to get some decent marks? I know the time period is really short but since I don’t have anything to do now I can give it my all.

Sincerely,

A student.

Doing Solved Papers of previous years may be helpful as well.

Sir,

I got compartment in Maths. It will be helpful if you could mail me previous 5 years Maths compartment question papers to my email id.

Kindly send email to me.

Thank you.

Please find the solved papers of previous years in Class 12 section at theopgupta.com

Sir, how to find the value of sin inverse(sin 2) = ?

Hello

I am a class 12th student & I am a student of Deeksha.

It is getting really hard to manage time & go about with the stress.

Could I get some help if possible??

Your help could be of great deed to me 🙂

Waiting for reply..

Hello Sir,

Thank you very much for uploading these formulas. Now I’m studying in 12th. If you upload anything related to 12th means, kindly send an E-mail for me.

Thank You.

Sir, I Just have a doubt what to do if we get sin[cos^-1(x^2)] ?

Substitute cos^-1(x^2) = A. Then, cos A = x^2. Find sin A to get your desired result as sqrt (1 – x^4).

Sir, I want to teach with you. So, plz sir can you give me some time? Plz, tell me.

Thank you

Thank you sir

Thanks for posting such a comprehensive mathematics materials.

Thank you!

Awesomeeeee.

Thanks a lot!!!

Thank you very much. It’s really useful.

Please give all formulas

Very Useful Materials…. Thanks a lot.

Only 4 topics are free, rest are all paid.

What’s the use of it then, because all the main chapters are paid.

Anyways it does have very good content, but I wish that all the topics should be free.

Thanks.

Thanks but I will be highly obliged if u can give me full formula of those chapter

You need to purchase the same.

Worst website ever..

We welcome your feedback and apologize for not being up to the mark for you. It shall be helpful if you let us know why do you think that “this website is worst”?

Sir,

Knowledge Is meant to be free… The reason behind Khan Academy (an Online tutorial Portal) being so successful is that it offers everything free.

If you really want to make money, then offer ads on your website.. why charge some meagre amount of money.

Anyways keep you good work up.

Highly Appreciated!

Thank you for the appreciation. We are in the process of offering a few more stuffs for no chagre to the math community in the future. Besides, here we are providing the Books (Printed Format) which costs us money in managing the Printing costs etc. and, hence can not be offered without covering the expenses.

Sir your formulae are cool that u should charge fee … though some are free whose experiences are so great that I get tempted to buy the books
