Before using the distance formula to calculate lengths of segments in the coordinate plane, the sophomores combined their knowledge of distance on a number line with the Pythagorean theorem to effectively calculate the length of a segment. After this we broke down the Pythagorean theorem to create the distance formula.

After familiarizing themselves with the three main trigonometric functions and their ratios, the seniors applied that knowledge to some real world situations. We worked on picking out important information and drawing a sketch to represent each problem before writing and solving any trigonometric equations.
