Tan of angle X = opp/adj.

Answer 2

In Geometry, the tangent refers to a line that touches a curve, usually a circle, at just one point.

The tangent to a circle is perpendicular to the radius drawn to the point of tangency.

If the tangent is horizontal, it means that there is either a maximum or a minimum value at that point.
