If cos(t) = where r < t <3, find the 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 i enter as sqrt; e.g. the square root of 2 should be written as sqrt(2). cos(2t) = sin(2t)= cos(-) = sin()=
