Find all solutions to the equation. c059=l Write your answer in radians in terms of 11:, and use the "or" button as necessary. Example: 9 = % +2k1r, FEE Z are = % +kI, RE Z v Find all solutions to the equation. oosB=1 Write your answer in radians in terms of It, and use the "or" button as necessary. if Help with this notation Example: 9 = % +2kn, kE Z or 9 = % +kIE, ICE Z Use the power reducing formulas to rewrite sin *6x in terms of the first power of cosine. Simplify your answer as much as possible. To indicate your answer, first choose one of the four forms below. Then fill in the blanks with the appropriate numbers. O sin 6x = - cosx + [cos[x X ? O sin 6x = [ + [cos[x + [cos]x O sin 6x = [ - [ cos[x O sin 6x = + cos xFind sin 2x, cos 2x, and tan 2x if tanx = and x terminates in quadrant II. 10 OVO sin 2x = X 5 ? cos 2x = tan 2x =7 Find all solutions of the equation in the interval [0, 21!). if ltanx : secx Write your answer(s) in radians in terms of It. If there is more than one solution, separate them with commas. The brightness of some stars can fluctuate over time. Suppose that the brightness of a certain star can be modeled by the following. B (t) = 7.6 + 10.6 sin 2 Tt 69 In this equation, B (t) represents the magnitude of brightness, and t is the time (in days). Suppose we start at t = 0 days. During the first 69 days, when will the star's magnitude of brightness be 15? Do not round any intermediate computations, and round your answer(s) to the nearest day. (If there is more than one answer, enter additional answers with the "or" button.) t = | days or X
