If `f(x)=(cos x-sin x)/(cos x+sin x)` then `f^(-1)(x)=`

If (x)=(cos x+i sin x)(cos3x+i sin3x)...(cos(2n-1)x+i sin(2n-1)x) then f(x) is

The range of f(x)=cos x-sin x is

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

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

If (x)=(cos x+i sin x)(cos2x+i sin2x)(cos3x+i sin3x)...(cos nx+i sin nx)= and f(1)=1, then f'(1) is equal to

f(x)=(1)/(sin x cos x) find ,f'(x)=?

If f(x)=2x+[x]+sin x cos x, Then f is:

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

if int e^(sin x)(x cos^(3)x-sin x)/(cos^(2)x)dx and f(0)=1 then f(pi)= is
