Simplify the following expression so that it is expressed entirely in terms of sine and cosine : sec(r ) tan- (x) = (sin(x))"(cos(x)) cot(z) csc2 (1) That is, find the values of a and b so that this equation holds. bIdentify the amplitude, phase, period, and mean in the function y = M + A cos 2" (x - $)) as shown on the graph below. 2 - 1.5 0.5 -41 -3x -2x - It 0 3 x 4 x X . The mean is M = . The amplitude is A = The period is P = and the graph completes P zi cycle(s) between 0 and 2x. . The phase shift is o = FORMATTING: The symbol a is denoted pi in Mobius.Consider the equation 005(51} = %. It has inniter many solutions. What is the smallest solution I greater than sr'? Answerz=|I |n. FDRHAITING: Remember that 1:1- is written as pi in the response area. Find all solutions of the following equation. 1031:: + 4} + log{z + 1} = log}. Hint: Check your answer{s} by plugging ithem into the above equation. FRATN-S: Write merits! of values of a: oath-seen square brackets [ and ]. if these is more than one, separate them by commas; eg. [143]. Answenz=l Inl
