Angle between two curves, inter math 1b, cbse, math web.

Angle between two curves can be find by using the tangents drawn through these two curves, touching at a common point.
Angle between two curves can be find using the angle made by the these two tangents passing through the two curves.
Angle between two curves can be made in the form of four cases. If slope of two tangents are equal, then two curves touch each other.
One of the angle between two curves is zero, then the angle depends upon the slope of the other curve.
In angle between two curves, the product of slopes of two curves is equal to -1, then the two curves are perpendicular to each other.
