3 - (1 point) If cos(t) = where < t < , find the 2 values of the following trigonometric functions. Note: Give exact answers, do not use decimal numbers. The answer should be a fraction or an arithmetic expression. If the answer involves a square root it should be enter as sqrt; e.g. the square root of 2 should be written as sqrt(2). cos (2t) = sin(2t)= cos (+) = sin() =
