Trigonometric Proofs Worksheet
Trigonometric Proofs Worksheet - In the last two chapters we have used basic definitions and relationships to simplify trigonometric expressions and equations. In this chapter we will look at more complex relationships that allow us to consider combining and composing equations. ( 2cos x + sin x ) + ( cos x − 2sin x ) ≡ 5 (**) 2.
