Use experimentation to solve problems with ellipses.

Exploring the Sine

The biggest topic of this course is trigonometry, which involves the functions sine, cosine, and tangent. You may have seen these before in the context of relationships in a right triangle (as shown below), but this course develops them in a fuller sense that allows us to link them to some of the most fundamental things in the universe, like springs, pendulums, light, and sound!
