Let f(x) =cosx sin2x. Then , min (f(x):-pilexlepi) is

If f(x) = |cos x- sin x| then find f'((pi)/(6))

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

Statement 1: Let f(x)=sin(cos x) in [0,(pi)/(2)]* Then f(x) is decreasing in [0,(pi)/(2)] Statement 2:cos x is a decreasing function AA x in[0,(pi)/(2)]

If f(x) = |cos x - sin x| , then f^(1)(pi/4) =

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

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

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

Let f(x)=e^(cos^-1sin(x+pi/3)) , then
