Finding+the+Equation+of+a+Tangent+Line

A tangent line is the exact representation of slope at a certain point on a curve. To find this line, we apply a derivative to any specific point.

Abstract/Overall Explanation

For example: We need to find the tangent line of the equation f(x)=3x 3 -6 at the point x=1. Here is the graph:
