`intsqrt((1+cos 3x)/(1-cos3x))dx=`

intsqrt((1-cos2x)/(1+cos 2x))dx=

Evaluate: (i) intsqrt((1+cos2x)/(1-cos2x))\ dx (ii) intsqrt((1-cosx)/(1+cosx))\ dx

intsqrt((cosx-cos^3x)/(1-cos^3x))dx is equal to (a) -2/3sin^(-1)(cos^(3/2)x)+C (b) 3/2sin^(-1)(cos^(3/2)x)+C (c) 2/3cos^(-1)(cos^(3/2)x)+C (d) none of these

intsqrt(1+cos 2x) dx

intsqrt(1-cos 2x) dx

intsqrt(1+cos 2x) dx

intsqrt(1-cos 2x) dx

If intsqrt((cosx-cos^3x)/((1-cos^3x)))dx=f(x)+c , then f(x) is equal to
