`(sinx-sin3x)/(sin^(2)x-cos^(2)x) = 2sinx`

int(sin^3x+cos^3x)/(sin^2xcos^2x)dx (A) sinx+cosx+c (B) tanx+cotx+c (C) secx-cosecx+c (D) sinx-cosx+c

sinx^(2)+sin^(2)x+sin^(2)(x^(2))

e^(x)((cosx-sinx)/(sin^(2)x))

(sinx+sin3x)/(cosx+cos3x) = tan2x

int(sinx. cos x)/(a^(2) cos^(2) x+b^(2) sin^(2) x)dx

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

If int(cos^(3)x+cos^(5)x)/(sin^(2)x+sin^(4)x)dx=p sinx-q/(sinx)-rtan^(-1)(sinx)+C then p+2q+r is equql to:

Prove that: (sin5x-2sin3x+sinx)/(cos5x-cos x)=tanx
