Challenging Q

sin^-1x + cos^-1x = π/2 not 0

But i have a proof using calculus

Think about it then i will give the solution

Its using integral calculus

Maybe we can solve........but we definitely can't prove

If u want us to prove that result, then u first prove either of the following:

0 = π/2

or

sin^-1x + cos^-1x ≠π/2

∫-1/√(1-x²)

Integrate it you will see it.

OR

Multiply and divide both sides by \frac{d}{dx}
