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.
Finding Multiple Sums and Differences of Angles. Given sinα= 3 5 ,0<α< π 2 ,cosβ=− 5 13 ,π<β< 3π 2 , sinα= 3 5 ,0<α< π 2 ,cosβ=− 5 13 ,π<β< 3π 2 , find.
Finding a Cofunction with the Same Value as the Given Expression. Write tan π 9 tan π 9 in terms of its cofunction. Solution. The cofunction of tanθ=cot( π 2 −θ ).
Verifying an Identity Involving Sine. Verify the identity sin(α+β)+sin(α−β)=2sinαcosβ. sin(α+β)+sin(α−β)=2sinαcosβ. Solution. We see that the left side of the equation includes the sines of the sum and the difference of angles.
Verifying an Identity Involving Tangent. Verify the following identity. sin(α−β) cosαcosβ =tanα−tanβ sin(α−β) cosαcosβ =tanα−tanβ. Solution. We can begin by rewriting the numerator on the left side of the equation.
Using Sum and Difference Formulas to Solve an Application Problem. Let L 1 L 1 and L 2 L 2 denote two non-vertical intersecting lines, and let θ θ denote the acute angle between L 1 L 1 and L 2 .
