Trigonometric Identities Teacher Resources

Six lessons comprise the Geometry Unit 7: Right Triangles unit module. In the first lesson, pupils review the Pythagorean Theorem and determine how to use the converse to determine whether a triangle is right, obtuse, or acute. Next,...

A precalculus playlist of 29-videos demonstrates the processes and includes step-by-step explanations of functions. The collection includes inverse trig functions, polar coordinates, graphing polar curves, parametric curves, analytic...

Starting with right triangles (SOH-CAH-TOA) and working up to the concept of radians, this collection introduces students to trigonometric ratios and supports them in learning to evaluate trigonometric functions.

Six lessons make up the Geometry Unit 9: Area of Polygons unit module. Pupils review the formulas for finding the area of parallelograms and triangles. They apply previous learning of trigonometric ratios and the Pythagorean Theorem to...

Everything calculus scholars need to know about derivatives can be found in this 31-resource playlist. The collection defines the derivative and includes derivative rules, chain rule, derivatives of trig functions, derivatives of...

Prepare high school mathematicians for the AP Calculus AB exam with a collection of 38 videos that can be used to introduce the topics or as a review. The videos focus on two processes; differentiating a function and integrating a...

Flip your classroom, or offer engaging visual aids to your lessons with a series of videos that explore the concept of trigonometry. After an introduction to the topic, high schoolers investigate reference triangles, unit circles, and...

The 17 resources in NASA’s Rockets Educator Guide allow young scientists and engineers to engage in experiments as they examine images of more than 2,00 years of rockets. Scholars then read articles that provide an overview of the next...

Imagine a world powered by wind! The 19 lessons in this curriculum set provide young environmental scientists the information they need to imagine just that. The series begins with a lesson on the difference between forms of energy and...

The 11 resources in the Math in Science playlist cover concepts introduced in a high school or college biology class. Topics include Comparing Metric Units of Measurement, Mass and Weight, Volume, and Length. Other videos focus on...

The three lessons in the Algebra II series Exploring Space Through Math expand learners’ knowledge of algebraic thinking and symbolic reasoning and encourage them to connect algebra and geometry. Activities include calculating the number...

The five resources in the Geometry Unit 11: Circles Unit Module are designed for the flipped classroom. Pupils watch videos that show how to apply concepts about circles, tangents, congruent chords and arcs, and intercepting arcs....
