6.5 Skill Builder: Trigonometric Identities

Work on the chain gang. The 11th installment in a series of 31 demonstrates how the chain rule and the quotient rule work together to find a derivative. Using a trigonometric function of a quotient involving exponentials as an example,...

This video introduces the basics of trigonometry. It starts by defining a right triangle and showing two different examples of finding the ratios of sine, cosine, and tangent using the SOH-CAH-TOA mnemonic. This resource could be used as...

Finding the inverse of trigonometric ratios is not the same as finding the reciprocal. The presentation introduces how to find the angle of a right triangle given sides. Part of a larger playlist on geometry, the video uses the inverse...

The story continues with more complex equations. Learners see that using the story method works even with multi-step equations. Pupils learn the process of undoing a description of a multi-step expression to solve an equation containing...

Multiply two monomial rational expressions and then rewrite the solution in simplest form. Multiplying seems straightforward, but what about the reducing part? Find the greatest common factor. Then divide the numerator by the GCF, and...

Investigate division within an algebraic term using an inquiry-based lesson. Individuals adjust sliders and watch as the simplification of the term changes. Questions help guide them to important conclusions.

There isn't a more popular geometry formula than the Pythagorean Theorem! Learners understand the special side relationships in a right triangle. They use the Pythagorean Theorem to find missing sides and to solve problems. They begin...

Continuation of video lesson using the basic trigonometric functions to determine unknown side lengths of a right triangle. Example shows using trigonometry as well as the Pythagorean Theorem to find the length of the third side of the...

For this calculus worksheet, students use differentiation to solve problems. They apply the quotient rule as they solve rational expressions. There are 19 questions with an answer key.

A couple of more examples of using Trig functions to solve the sides of a triangle. This video use the basic trigonometric functions to determine unknown side lengths of a right triangle. Example shows using trigonometry as well as the...
