Angle of Intersection of Two Curves
Let y = f1( x) and y = f2( x) be the two curves, meeting at some point P( x1,
y1), then the angle between the two curves at P( x1, y1) = The angle between the tangents to the curves at P( x1, y1)
The other angle between the tangents is( 180— θ). Generally, the smaller of these two angles is taken to be the angle of intersection. ∴ The angle of intersection of two curves θ is given by
