The trigonometric function of an angle is the value of the trigonometric functions of sine, cosine, tangent, cosecant, secant and cotangent of that angle. To use the unit circle in evaluating the trigonometric functions of an angle, we first identify the coordinate points of the terminal side of the sector formed by the angle on the unit circle. Next, we draw a triangle with the terminal side of the reference angle as the hypothenuse, the positive or the negative x-axis (as the case may be) as the side adjacent to the reference angle and a line parallel to the positive or the negative y-axis (as the case may be) as the side opposite the reference angle. The x-coordinate of the coordinates of the terminal point formed by the angle on the unit circle represents the adjacent side of the triangle while the y-coordinate represent the opposite side of the triangle. We can then use the SOHCAHTOA principle to evaluate the trigonometric functions of the reference angle.\n
