We recall the standard trig identity for secx. Therefore the integral of secx is the same thing, or identical in other words. At this point, we can simply look up the integral of secx in There are several ways to integrate 1/cosx, or secx; just look on Google. You can try [tex]\frac{1}{cosx}*\frac{cosx}{cosx} = \frac{cosx}{cos^2x} = \frac{cosx}{1-sin^2x}[/tex] and use u = sinx. Or working with secx, use the "clever substitution," as my calc book says, u = secx + tanx, du = sec 2 x + secxtanx dx. Det är för att när du deriverar -1 2 cos (2 x), får du inre derivata 2.
