`f(x)=cos x + sin x "(in)" [ 0, 2pi]` में

If f(x)=cos x+sin x . find f ((pi)/(2)) .

If f(x)=cos x+sin x, find f((pi)/(2))

cos(2pi -x) cos (-x) - sin(2pi +x) sin (-x) = 0

If f(x)=|cos x-sin x|, then f'((pi)/(2)) is equal to

Let the function f(x) = sin x + cos x , be defined in [0, 2pi] , then f(x)

Verify Rolle's theorem for each of the following functions: (i) f(x) = sin 2x " in " [0, (pi)/(2)] (ii) f(x) = (sin x + cos x) " in " [0, (pi)/(2)] (iii) f(x) = cos 2 (x - (pi)/(4)) " in " [0, (pi)/(2)] (iv) f(x) = (sin x - sin 2x) " in " [0, pi]

f(x)=sqrt(3)cos x + sin x, x in [0, (pi)/(2)] is maximum for x = …………

If f (x) =2x, g (x) =3 sin x -x cos x, then for x in (0, (pi)/(2)):
