No explanations needed, only the correct solution, thank you:

Use the fundamental identities to simplify the expression. (There is more than one correct form of the answer.) cos( x x) sec(x) 2 E Write the logarithmic equation in exponential form. For example, the exponential form of logs(25) = 2 is 52 = 25. 4 log32(16) = E 5 Find all solutions of the equation in the interval [0, 2x). (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.) 9 cos x + 9 sin x tan x = 18 X =
