Trigonometry - What is a Radian?
This PowerPoint presentation investigates the fundamental trigonometric angle measurement known as a radian. You will learn what a radian is, how it is derived, and the relationship between radians and degrees.
After learning the definition of an angle you will then review some basic geometric concepts. Using the definition of an angle and the geometric concepts a radian is defined and an animation shows how a radian is derived in a circle.

Unit Circle Guided Discovery
This is designed for use with a Pre-Calculus class but can be used with any class studying the unit circle and trigonometry. The students are asked to find the sine, cosine, and tangent of the point typically associated with a unit circle. Students should be familiar with finding trig ratios by plotting points and using reference angles and the related triangles. The term "reference angle" is not used, however. Then students plot the points and discover the unit circle. I use Desmos to plot

Trigonometric Functions: Theory and applications
The study of trigonometric functions serves as a cornerstone in mathematics, providing a means to represent angles numerically. The six primary trigonometric functions—sine, cosine, tangent, cosecant, secant, and cotangent—define relationships between the sides of a right-angled triangle and resonate throughout various mathematical and scientific domains. Visualizing these functions through trigonometric graphs reveals their periodic nature, amplitude, and phase shifts. Additionally, trigonometr
