Cos theta sec theta
WebThe idea behind this substitution is to "cancel out" part of the denominator with the differential term (dx (dx in terms of d\theta) dθ) in order to integrate a smaller expression. When applied properly, something will cancel out, since \tfrac {dx} {d\theta} = 1 + x^2, dθdx = 1+x2, where x = \tan\theta x = tanθ. Evaluate.
