Curated OER
The Laws of Sines and Cosines Made Simple!
Students study the law of sine and cosine. For this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.
Curated OER
Extrema on an Interval
Students explore maximum and minimum points, slopes and tangents. For this Pre-Calculus lesson, students solve optimization problems and find rates of change.
