Evaluate the six trigonometric functions for the given real number

The video tutorial explains how to evaluate the six trigonometric functions for the angle 5π/4. It begins by graphing the angle on the unit circle and identifying its position in the third quadrant. The tutorial then determines the coordinate point for 5π/4, which is a reflection of the point for π/4. Using this coordinate, the video demonstrates how to evaluate the sine, cosine, tangent, cosecant, secant, and cotangent functions, including rationalizing denominators and simplifying expressions.
