Evaluate `int(sec^(2)xdx)/(sqrt(tan^(2)x+4))`.

Using the result int(dx)/(sqrt(x^(2)+a^(2)))=log|xsqrt(x^(2)+a^(2))|+C , Evaluate int(-"cosec"^(2)xdx)/(sqrt(cot^(2)x+9))

Evaluate: int sec^(3)2x dx

Evaluate: int sec^3 2x dx

Evaluate int_(0)^(2)7^xdx

Evaluate : int sec^2 2x dx

Evaluate int(tanx dx)/(sqrt(2+3tan^(2)x)).

Integrate the function (sec^(2)x)/(sqrt(tan^(2)x+4))

Evaluate: int 2sin^(-1)xdx

Integrate the functions (sec^(2)x)/(sqrt(4-tan^(2)x))

int (sec^(2) x)/( tan^(2) x - 1) dx is
