(i) int (3x^2)/(x^6+1) dx (ii) int (3x)/(1+2x^4) dx

int (x+1)/(2x^2+3x+4) dx

int(2x^(n-1))/(x^(n)+3)dx

Evaluate int (2x^(3)-1)/(x^(4)+x)dx

int(x^4-3)/(x^2+2x+1)dx

Prove that int(dx)/((1+x^(2))^(n))=(1)/(2(n-1))[(x)/((1+x^(2))^(n-1))+(2n-3)int(dx)/((1+x^(2))^(n-1))],n in N Hence,computer the value of int cos^(4)xdx

int x^(3)cos x^(4)dx int nx^(n-1)cos x^(n)dx

int(2x^(3)+1)/((2x^(4)+4x+1)^(3))dx

int(2x^(3)+1)/((2x^(4)+4x+1)^(3))dx

If int(tan^(2)x+tan^(4)x)dx=((1)/(n))tan^(n)x+c, then n=
