If y = Sin-1 √(1 + sin x) + √(1 - sin x)√(1 + sin x) - √(1 - sin x) and -3π2 < x < -π2, then dydx =

If y = √(xa) + √(ax), then 2xy dydx is equal to:

If f(x) = (3 + x1 + x)2 + 3x, then f'(0) is equal to:

If y = sin-11√(x+1), then dydx =

The value of ddx{sin2(cot-1 √(1 + x1 - x))} is equal to:

If f(x) is an even function and f'(0) exists, then the value of f'(0) will be:
