(1 point) Given cos(a) = 0/2 and O < < Tt/2, find the exact values Of the remaining five trigonometric functions. Note: You are not allowed to use decimals in your answer. sin(a) = cot(a) = Answer(s) submitted: (incorrect) Problem 5. (1 point) For the acute angle 0 with cot 0 1, find (give exact answers. NO DECIMALS. If the answer involves a square root it should be entered as sqrt . E.g. the square root of 2 should be written as sqrt(2)) sin O = coso = tan 0 = seco csc 0 Answer(s) submitted: (incorrect) Problem 6.
