Ck 12: Algebra Ii: 4.8 Pythagorean Identities

This section introduces radians an alternative to degrees as a way to measure the rotation around a circle. It also begins to draw connections between radians and trigonometric identities.

This section explores right triangles with three lengths that are considered Pythagorean Triples, and also investigates how some right triangles can have lengths that are not Pythagorean Triples.

Learn to analyze examples of claims presented in the media that involve estimating a population proportion and population mean.

This section addresses how to solve different types of logarithmic equations. It explores how to condense expanded equations and how to convert logarithmic equations into exponential ones.

This section explores the process of multiplying polynomials, and applies this process to real-life models.

Activities in this lesson explore how to identify the coordinates where special right triangles intersect with the unit circle in all four quadrants, use both degrees and radians to identify angles, and explore angles of different sizes...

This section explores the relationship between right triangles, circles, and trigonometry. It investigates how a right triangle that is set inside a circle and rotates around the circle is connected to trigonometric functions and their...

Use this tutorial to revisit right triangle trigonometry.

This lesson will explore how real life examples of periodic behavior can be modeled with Trigonometric Functions.

Explore how changes to the equations of sine and cosine functions affect the graphs of the functions through transformations (stretches and shifts).
