Coordinates of a Reflected Point Applet (Week of 12/3)

Sequence Applet (Week of 11/8)

Triangle Applet (Week of 11/1)

Slider Applet (Week of 10/25)

My working of problem...

10 (p.1): The value chosen for AE determines the value of DE+EC. Letting x stand for AE (and 30-x for EB), write a formula for this function. Then enter this formula into your calculator, graph it, and find the value of x that produces the shortest path from D to C through E.

The equation for DEC

The shortest path from D to C through E

Angles AED and BEC add together to form a 90 degree angle.
