Find coterminal reference and quadrant
Web1. Find the ordered pair for 240 ∘ and use it to find the value of sin240 ∘. sin240 ∘ = − √3 2. As we found in part b under the question above, the reference angle for 240 ∘ is 60 ∘. The figure below shows 60 ∘ and the three other angles in the unit circle that have 60 ∘ as a reference angle. Figure 1.7.3. WebThe student uses the steps below to find cos mc026-4.jpg. Step 1 Find the quadrant in which P (a, b) lies: P (a, b) is in Quadrant IV. Step 2 Use the point and the Pythagorean theorem to determine the value of r: mc026-5.jpg, but since r must be positive, mc026-6.jpg. Step 3 Determine cos mc026-7.jpg.
