1.	)State the signs of trigonometric functions(i) sin (159(ii) cos
Answer» 1. positive. sin(x) is positive from 0 to 180 degree.2. 11 * 180 / 9 = 220 degrees. cos(x) is negative in the range(90, 270). therefore, answer is negative. but answer is possitive (ii) would also be positive as there is a conjugate sign.
