Webb• We will analyze trigonometric identities numerically and graphically. • We will discuss techniques used to manipulate and simplify expressions in order to prove trigonometric identities algebraically. Recall: A trigonometric identity is an equation formed by the equivalence of two trigonometric expressions. WebbWe will now look at three examples of using each of the Pythagorean identities to answer questions. Simplify sin x cos 2 x = sin x − 1 and find the value of x: ＜＜ 0 ＜ x ＜ 2 π. For this, we will need to use the first Pythagorean identity: sin 2 θ + cos 2 θ = 1 and rearrange it: cos 2 x = 1 − sin 2 x. We can now substitute 1 − ...

We will use this to obtain the sine of a double angle. If we take the left hand side (LHS): sin (α + β) and replace β with α, we get: sin (α + β) = sin (α + α) = sin 2 α. Consider the RHS: sin α cos β + cos α sin β. bird hides near tavistock
