Document Summary

6. 5 circular functions - graphs and properties notes: sterling. Provide a generalization to each of the key terms listed in this section. 1 = s. if the radius is 1, then, = s the radius is 0, then will be unde ned sinze the 0 would be in the denominator. When the radius is 1, then = s r = s r = s ( 1) = s. What would the rotation"s center, in radians, when you have a point that"s 5 meters from the rotation"s center while traveling at 10 meters? s r. When you have any real number, which can be expressed with s, that can help gure out a point, which is normally in the form of (x, y), on a unit circle and can be explained by the following: = x y x 6= 0 y 6= 0 x 6= 0 y 6= 0.

One of the most visible is R Leonis; its brightness is modeled by the function b) -7.9-2.1 measured in days. a) Find the period of R Leonis. b) Find the maximum and minimum brightness c) Graph the function b. 2. where t is 3. (20 points) A movie theater has a 25-foot-high screen that is 8 feet above eye level. If you sit too close, your viewing angle is too small. If you sit too far back, the image is too small. If you sit x feet back from the screen, your viewing angle, Î¸, is given by Find the viewing angle, in radians, at distances of 5 feet, 10 feet, 15 feet, 20 feet, and 25 feet. Then graph the function in a graphing calculator with a viewing window of [0, 50, 10] by 10, 1, 0.1]. Use the calculator to find the distance at which you have a maximum viewing angle. [Hint: Viewing windows are written as [minmax Xscl by Dmin.Jmax Yscil. These values can be adjusted by pressing the WINDOW button on the calculator. To find a maximum, press 2ND TRACE, choose maximum, move to the left of the maximum and press ENTER, move to the right of the maximum and press ENTER, and then press ENTER again.
