int_(0)^(1) cot^(-1) (1-x+x^(2))dx=

int_(0)^(1)cot^(-1)(1-x+x^(2))dx

int_(0)^(1)cot^(-1)(1-x+x^(2))dx

If int_(0)^(1) cot^(-1)(1-x-x^(2))dx=k int_(0)^(1) tan^(-1)x dx , then k=

If int_(0)^(1) cot^(-1)(1-x+x^(2))dx=k int_(0)^(1) tan^(-1)x dx , then k=

If 2int_(0)^(1)tan^(-1)xdx=int_(0)^(1)cot^(-1)(1-x+x^(2))dx then int_(0)^(1)tan^(-1)(1-x-x^(2))dx is equal to

If 2int_(0)^(1)tan^(-1)xdx=int_(0)^(1)cot^(-1)(1-x+x^(2))dx then int_(0)^(1)tan^(-1)(1-x+x^(2))dx=
