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

If f(x)=|cos x-sin x|, find f'((pi)/(6)) and f'((pi)/(3))

If f(x)=|cos x-sin x|, find f'((pi)/(6)) andf '((pi)/(3))

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

If f(x)=|cos x-sin x|* then f((pi)/(4)) is

If f(x)=|cos x-sin x|, then f'((pi)/(4))=

Given f'(x) = (cos x )/( x ), ,f ((pi)/(2)) =a, f ((3pi)/(2))=b. Find the vlaue of the definite integral int _( pi//2) ^(3pi//2) f (x) dx.

If f'(x)=k(cos x-sin x),f'(0)=3 and f((pi)/(2)) find f'(x)

f(x)=int x^(sin x)(1+x cos x*ln x+sin x)dx and f((pi)/(2))=(pi^(2))/(4) Then the value of |cos(f(pi))| is

If f(x)=cos x cos2x cos4x cos(8x)*cos16x then find f'((pi)/(4))

If f(x)=|x|^(sin x|), then find f'(-(pi)/(4))
