cos^(-1)((3cos x-4sin x)/(5))

Differentiate the following w.r.t. x : cos^-1 ((3cos 3x-4sin3x)/5)

Simplify each of the following: cos^(-1)((3)/(5)cos x+(4)/(5)sin x), where -(3 pi)/(4)<=x<=(pi)/(4)

int(3sin x-2)cos x(dx)/(5-cos^(2)x-4sin x)

If cos^(-1)(3/5)-sin^(-1)(4/5)=cos^(-1)x then x=

If cos ^(-1)((3)/(5))-sin ^(-1)((4)/(5))=cos ^(-1) x, then x=

sin4x=4sin x cos^(3)x-4cos x sin^(3)x

Differentiate the following w.r.t x: cos^(-1) (frac { 3 cos 3x - 4 sin 3x}{5}')
