9.2 SUM AND DIFFERENCE IDENTITIES - OPENSTAX
From openstax.org
- Finding the Exact Value Using the Formula for the Cosine of the Difference of Two Angles. Using the formula for the cosine of the difference of two angles, find the exact value of cos( 5π 4 − π 6 ).
- Finding the Exact Value Using the Formula for the Sum of Two Angles for Cosine. Find the exact value of cos(75°). cos(75°). Solution. As 75°=45°+30°, 75°=45°+30°, we can evaluate cos(75°) cos(75°) as cos(45°+30°).
- Using Sum and Difference Identities to Evaluate the Difference of Angles. Use the sum and difference identities to evaluate the difference of the angles and show that part a equals part b.
- Finding the Exact Value of an Expression Involving an Inverse Trigonometric Function. Find the exact value of sin( cos −1 1 2 + sin −1 3 5 ). sin( cos −1 1 2 + sin −1 3 5 ).
- Finding the Exact Value of an Expression Involving Tangent. Find the exact value of tan( π 6 + π 4 ). tan( π 6 + π 4 ). Solution. Let’s first write the sum formula for tangent and then substitute the given angles into the formula.
