2.

Inverse functions

This is a set of apps devoted to illustrate the symmetry between the graph of a function and the graph of its inverse. Also helpful to understand the notion behind domain restrictions.

  • 1. The graph of the inverse function

The graph of the inverse function

3.

Transformations of a function

An app devotet to illustrate what happens to a function's graph when its parameters are modified.

  • 1. Reflections, strechings and compressions

Ellipses and hyperbolas by means of perpendicular bisectors

On a sheet of paper draw a circle and name its center "F_1". Then pick a point and call it F_2.[br][br]Fold the paper so that F_2 meet the circumference at least 50 times (25 points and their opposite through the diameter):[br][br]What do you get if the distance between F_1 and F_2 is less than the circle radius?[br]What do you get if the distance between F_1 and F_2 is greater than the circle radius?[br]What do you get if the distance between F_1 and F_2 is equal than the circle radius?[br][br]By the way, did you notice the relation between the circle radius and the addition or the difference between the highlighted distances?
