When given a point, how to find the triangle to evaluate for the 6 trig functions

The video tutorial discusses evaluating trigonometric functions without a triangle by using reference angles. It explains the concept of reference angles, how to create right triangles from them, and how to evaluate trigonometric functions using these triangles. The tutorial also covers the calculation of sine, cosine, and tangent, and their reciprocals, using given points and reference angles.

What is the significance of the reference angle in trigonometry?

Describe the relationship between sine of an angle and sine of its reference angle.

Explain how to create a right triangle using a reference angle.

What are the steps to find the hypotenuse of a right triangle given its sides?

How do you evaluate the six trigonometric functions using a right triangle?
