- check out http://mcraefamily.com/MathHelp/CalculusIntegralTableOfIntegralsSqrtTan.htm
for details.
using the substitution v = sqrt(tan(x)),
so dv = sec^2(x)/(2 sqrt(tan(x))) dx,
eventually gives
(sqrt(2)/4) ln(tan(x)-sqrt(2tan(x))+1)
+ (sqrt(2)/2) atan(sqrt(2tan(x))-1) +
(-sqrt(2)/4) ln(tan(x)+sqrt(2tan(x))+1)
+ (sqrt(2)/2) atan(sqrt(2tan(x))+1) + C
