Galileo wanted to release a wooden ball and an iron ball from a height of 150 meters and
measure the duration of their fall.
He found a plane with an incline of 15° that
he could climb until he gets to an altitude of
150 m.
How far should Galileo walk up the inclined
plane?

What is the reflection image of (5,-3) across the line y = -x?

Sketch one cycle if the cosine function y=2cos2theta
