Find the coordinate point of the given angle

The video tutorial explains how to find the coordinate values for an angle t = π / 3 using the unit circle. It covers the basics of the unit circle, focusing on the first quadrant, and demonstrates how to locate π / 3 on the circle. The tutorial concludes by calculating the coordinate values, which are x = 1/2 and y = √3/2.
