`(sin x + cos x)/(sin x - cosx)` का समाकलन कीजिये -

int(sin x+cosx)/(sin x-cos x)^2dx

cosx - sin3x = cos2x

int(cosx+sinx)/(sin x-cos x)dx=

int (cos^(2)xsin x)/((sin x- cosx))dx

int((cosx+sinx)dx)/(sin x-cos x)

What is the value of [(sin x + sin y)(sin x - sin y)]//[(cosx + cosy)(cosy- cosx)] ? [(sin x + sin y)(sin x - sin y)]//[(cosx + cosy)(cosy- cosx)] का मान क्या है?

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?

sinx + cosx = (cos2x)/(1-sin2x)

int (cosx + x sin x)/(x (x + cos x)) dx =

cosx + sinx = cos2x + sin2x
