Master Writing a single trigonometric expression using sum and difference formulas

The video tutorial explains how to use sum and difference formulas for trigonometric functions like sine, cosine, and tangent. It covers identifying the correct formula based on given expressions and demonstrates how to apply these formulas to angles in both degrees and radians. The tutorial provides step-by-step examples to help learners understand the process of rewriting expressions as single trigonometric functions of an angle.

How do you apply the sine and cosine formulas when the angles are given in degrees?

Describe the process of finding common denominators when dealing with radians in trigonometric expressions.

What steps do you take to rewrite an expression involving tangent using the sum and difference formulas?
