int(dx)/(cos^(2)x(1-tan x)^(2))

int(1)/(cos^(2)x(1-tan x)^(2))dx

If int(1)/(cos^(2)x(1-4tan^(2)x))dx=K log|(1+2tan x)/(1-2tan x)|+c, then K=

int(dx)/((1+cos2x)(1-tan^2 x))=

int(cos^(2)x)/(1+tan x)dx

int(1)/(1+3cos^(2)x)dx=(1)/(2)tan^(-1)((tan x)/(2))+c

int (cosecx)/(cos^(2) (1+ log tan (x/2)) dx =

If int(dx)/(cos2x+3sin^(2)x)=(1)/(a)tan^(-1)(b tanx)+c, then ab=

int(1+tan^(2)x)/(1-tan^(2)x)dx=....

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

Evaluate: (i) int(1)/(sqrt(tan^(-1)x(1+x^(2))))dx (ii) int(sqrt(tan x))/(sin x cos x)dx
