Evaluate the six trigonometric functions for the given real number

The video tutorial explains how to evaluate trigonometric functions at the point 3π/2 using the unit circle. It covers the identification of coordinate points and the evaluation of sine, cosine, and tangent functions. The tutorial also addresses reciprocal functions like cosecant and cotangent, highlighting cases where values are undefined.

What is the significance of 3π/2 on the unit circle?
