Question

Differentiate: y=(sec^2)x + (tan^2)x

Answer 1

Can't we solve it before proceeding further???

Answer 2

what does that mean

Answer 3

\[\sec^2(x) = 1 + \tan^2(x)\]

Answer 4

This will give us :

\[y= 1 + 2\tan^2(x)\]

Answer 5

easier now we can use chain rule

Answer 6

Yep, you can..

Answer 7

Oh, I see. Thank you!

Answer 8

You are welcome dear..
