int x^3 (sec^2x-tan^2x)dx

int e^x sec e^x dx

Evaluate : int(sec^2x)/(3+tanx)\ dx

Evaluate: int(sec^2x)/(3+tanx)\ dx

int(sec^(2)x+tan^(2)x)dx

Evaluate: (i) int(sec^2x)/(tanx+2)\ dx (ii) int(2cos2x+sec^2x)/(sin2x+tanx-5)\ dx

If int e^(sec x)(sec x tan x f(x)+(sec x tan x + sec^(2) x))dx = e^(sec x)f(x) + C , then a possible choice of f(x) is
