Dx in integration

WebThe dx is not simply a notational delimiter for the end of the integrand (i.e. "full stop"), it's … 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.
