Answer 1

hii frnd..

Tangent Line as Limiting Position ofSecant Lines. This applet shows that tangent line at a point P is obtained aslimiting position of secant lines through the point P. Use slider a to select point of contact P. Use button on bottom left of the geometric view to start and pause the animation.

hope it helps u (:

Answer 2

If it intersects the curve in two different points, as in the secant of a circle, the segment of the secant between the points is called a chord. The limiting position of a secant, if such a limit exists, is called the tangent to the curve or surface at that point.
