Learn how to construct the unit circle

The video tutorial explains how to construct and understand the unit circle, focusing on the conversion between degrees and radians, and the calculation of angles using fractions of π. It covers the basic coordinates, adding angles in increments of 45 and 30 degrees, and provides corrections for common mistakes.

How do you calculate the angles in the unit circle by adding 45 degrees?

What is the relationship between degrees and radians for 30 degrees?

What is the angle corresponding to 7π/6 in degrees?
