int (cot x)/((cosec x - cot x)) dx = ?

Find the following integrals. i) int(sin x+cos x) dx ii) int( cosec x(cosec x+cot x) d x iii) int( 1-sin x)/(cos ^(2 )x) d x

Show that : int (dx)/(1 - cosx) = - ("cosec"x + cot x) + c

int cosec^2 x dx=- cot x

Write down the integral of the following (i) sinx+cos x (ii) cosec x (cosec x + cot x)
