In this video, we introduce one of the most important foundational ideas in Precalculus: angle measurement. You’ll learn how to convert between degrees, radians, and revolutions, and understand how these units are related.
We’ll walk through:
What degrees, radians, and revolutions actually represent
Why radians are used so often in higher math and calculus
The key conversion formulas
Step-by-step examples of converting between each unit
By the end of this lesson, you’ll be comfortable switching between all three forms and ready for trigonometry and calculus concepts that build on them.
📌 Key formulas:
180∘ = 𝜋 radians
1 revolution = 360∘ = 2𝜋 radians
This video is perfect for Precalculus students, Algebra 2 students transitioning into trig, or anyone who wants a clear refresher on angle units.
