Needs Corrections Make sure that you show all of your work! 1. Solve cos = 0.83 algebraically over the domain 0 ≤ < 360° Trigonometric Equations and Identities Assignment 1 2. Solve 6 sin = 1 + 9sin () algebraically over the domain 0 ≤ < 2. 3. Solve 2 tan 3 = 7 algebraically over the domain ℝ. (All real numbers) Trigonometric Equations and Identities Assignment 1 4. Solve 3 ! = sin ( + 2) graphically and explain why we don’t have periodic solutions to this equation when we often get periodic solutions to other equations. Either paste an image of your graph on this page, or explain your window parameters and the steps you took to solve. Trigonometric Equations and Identities Assignment 1 5. The London eye is 135m at it’s highest point. At it’s lowest point it is about 3m off the ground. It takes about 30 minutes to revolve entirely. Across the river, Big Ben is about 96m tall. If you were to take a ride on the London eye, for how long were you higher than Big Ben? Trigonometric Equations and Identities Assignment 1 6. Solve 8 ! − 6 cos + 1 = 0 over the domain ℝ. Give exact answers where possible. ...
