EXAMPLES – Simplifying Trig Expressions * Simplifying a trigonometric expression means that the expression is written using the fewest trigonometric functions possible and as algebraically simplified as possible. This may mean writing the expression as a numerical value. EXAMPLES – Simplifying Trig Expressions
