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

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

3cos x+4sin x=5

The number of solutions of the equation sin^(5)x-cos^(5)x=(1)/(cos x)-(1)/(sin x)(sin x!=cos 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=

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

What is the value of [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] ? [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] का मान क्या है?

If 3 sin x + 5 cos x =5 , then what is the value of (3cos x - 5sin x) ?

int ((4-5sin x) / (cos ^ (2) x) + (1) / (sin ^ (2) x cos ^ (2) x)) dx
