Angle Between Two Curves
The angle of intersection of two curves is defined as the angle between the two tangents at the point of intersection. Let y = f(x) and y = g(x) be two curves and P(x0y0) be their point of intersection. Also let ψ and ϕ be the angles of inclination of the two tangents with the x axis and let θbe the angle between the two tangents
Then tan θ =
