How to find the acute angle between the curves — Krista King Math

If we want to find the acute angle between two curves, we’ll find the tangent lines to both curves at their point(s) of intersection, convert the tangent lines to standard vector form and then use the formula for the acute angle, given by cos(theta), where a and b are the given vectors, a•b is the d
