int sin^(-1)(cos x)dx=cdots cdots

int(sin x)/(1-cos x)dx

int(sin x)/(1+cos x)dx

int (1)/(cos x+ sin x)dx=

int 1/(sin x cos x) dx

int(1)/(sin x-cos x)dx

int (sin x)/(1 + cos x) dx .

int (1) / (sin x cos x) dx

int (1) / (cos x-sin x) dx

int(1)/(sin x+(cos x) dx

If I_(m,n) = int cos^m x cdot cos nx cdot dx show that (m + n) I_(m,n) = cos^m x cdot sin nx + m I_(m - 1, n-1)
