Suppose a right triangle produces the following relationship for cot(0). Use this relationship to answer the questions. Note - the questions can be answered independently of each other. cot (8) (a) Express tan (0) in terms of A. You must use an upper case letter A. tan (0) (b) Express A in terms of cot(0). 6 - 6cot(0) cot (8) OA= OA= 6 A + 6 = OA 1-6cot(0) cot (0) OA = OA= cot (0) - 6 cot (0) 6cot (0) 1 cot (8) 6 - cot(0) cot (0)

#5 How do I write it out?

#4 Write tan (sin-1 x), |x| < 1, as an algebraic expression in terms of x. Explain your answer. Explain, in your own words, how you can solve a right triangle when any two sides are given.

Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [-T, π). Then use that angle to determine the exact value from the unit circle. If undefined, write DNE. sec(-25) = sec( csc (¹7) = csc ( sin(- 17 ) = sin([])=[ sec (³) = sec ( Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [0, π). Then use that angle to determine the exact value from the unit circle. If undefined, write DNE. cot (37) = cot( tan (9) =tan(| =
