How to evaluate for cos without using a calculator or the unit circle
👉 Learn how to evaluate trigonometric functions of a given angle. Given an angle greater than 2pi in radians, to evaluate the trigonometric functions of the given angle, we first determine the smallest positive coterminal angle of the...

Determining clockwise vs counter clockwise rotations
👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

Introductory Angular Velocity Problem - A Turning Bike Tire
The wheel of a bike rotates exactly 3 times in 12.2 seconds. What is the average angular velocity of the wheel in (a) radians per second and (b) revolutions per minute?
Curated Video
Rotations about a Vertex
In this short video we will learn how to rotate a figure about a vertex in the coordinate plane. We will learn that the center of rotation is about a fixed point, a vertex, rather than the origin of the coordinate plane. The vertex...

Rotations (Identify the relationship between two numerical patterns derived from descriptions/rules in problems and graph them)
Let’s say we have a ceiling fan, and a washing machine and we want to compare the pattern of rotation of the fan and the drum in the washing machine over time.
