Question

Define Tangent..(≧▽≦)(≧▽≦)​

Answer 1

Answer:

a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.

Answer 2

Answer:

In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. ... The word "tangent" comes from the Latin tangent "to touch".
