The unit circle definition of trigonometric functionLesson Planet
9 mins 10th - 12th
In this video, Sal shows how the sine and cosine of an angle are defined on the unit circle. He inscribes a 30-60-90 triangle in the unit circle and explains how one can use SOH-CAH-TOA to find the coordinates on the circle.
Trigonometric Identity ProofsEngageNY
10th - 12th CCSS: Designed
Proving a trig identity might just be easier than proving your own identity at the airport. Learners first investigate a table of values to determine and prove the addition formulas for sine and cosine. They then use this result to...
Putting the Law of Cosines and the Law of Sines to UseEngageNY
11th - 12th CCSS: Designed
Use the Law of Cosines and the Law of Sines to solve problems using the sums of vectors. Pupils work on several different types of real-world problems that can be modeled using triangles with three known measurements. In the process,...
Integrals with Odd Powers of Sine and CosineLesson Planet
11th - 12th
Students review the power rule for integrals. They watch as the teacher demonstrates several problems. Students describe problems as an integral of u^n or du/u. They discuss problems that are not u^n because of the absence of a...
Sine SolutionLesson Planet
11th - 12th CCSS: Adaptable
New ReviewHow many times can eager mathematicians catch the waves? Pupils find the solutions of three different trigonometric equations. They then determine the effect of the slope of a line that intersects a trigonometric function and the number...
