Inverse Relation and Derivatives
- Kenneth Wright
Visualize a function and its inverse function. Note the point on the function (open dot) and point on the inverse relation (red) are related. How so? Also, the tangent line for the point on the function graph is related to the tangent line on the inverse relation graph. How so?
Grab the open dot to manipulate the "test" point on the function graph. Its counterpart on the inverse function will move accordingly. Each dot actually "mirrors" the position of the other with respect to the y = x line.
