Let’s find h first. By definition, cos(15°) = 12/h so h = 12/cos(15). To finish, we need the cosine of 15 degrees which requires a calculator. This tells us cos(15°) is about .966 so. h = 12/.966 = 12.42. We now have two out of three sides. We can get y either with the Pythagorean Theorem or …

The maximums and minimums occur every 2π radians. Maximums: when x= πn where n is an even integer. Minimums: when x=πn where n is an odd integer. Using your graph, find the value of cos . Cos = Find all values of θ, such that - occurs when x = +2π and when x = + 2π. Using your calculator, graph sin x and cos x on the same axis.
