Question

x = asin2t(1+cos2t)

y = bcos2t(1-cos2t)

Find dy/dx at t = pi/4 and t = pi/3

Find k if f(x) ={cos²x-sin²x-1÷root of 1+x²-1 continuous at x=0

(a x-y)x+y(a y-z)y+z(a z-x)z+x

• (a x-y)x+y(a y-z)y+z(a z-x)z+x

(a x-y)x+y(a y-z)y+z(a z-x)z+x

Hello sir,

First of all I am very thankful for your free videos particularly on maths and also thankful to your efforts you are making in revolutionizing the education system.

It is highlyappreciable.

But sir there is one request or suggestion that there are some students like me who are weak in mathematics, so you are requested to please clear basics first and elaborate the explanation.

Thank you sir.

Thank you for Ur videos Davneet Singh

Hello sir !

                 I have two problems related to Volume of Cone and Volume of Sphere.How can we prove the Volume of cone is 1/3Πr^2h?And same as Volume of Sphere

4/3Πr^3 ?Theoretically not practically. Plz solve this problem. It will help me a lot!
