Usingthe Sum and Difference Formulas for Cosine. Finding the exact value of the sine, cosine, or tangent of an angle is often easier if we can rewrite the given angle in terms of two angles that have known trigonometric values. We can use the special angles, which we can review in the unit circle shown in Figure 2.
Andwhere it's terminal ray intersects the unit circle, the X and Y coordinates of this point are what specify the cosine and sine. So the coordinates of this point are going to be the cosine of pi over four radians is the X coordinate and the sine of pi over four radians is the Y coordinates, sine of pi over four.

Thethree trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles. The sine and cosine rules calculate lengths and angles in any triangle.
Trigonometryfunctions; Reciprocal trigonometric functions; Inverse trigonometric functions Trigonometry functions. The main trigonometric functions are sine, cosine, and tangent, often written as sin(x), cos(x), and tan(x).The common thing for them is that they express the ratios between different sides of a right-angled triangle, from the point of view of the angle of interest, and thus some
Letus refer to Figure 1 and define the three basic trigonometric ratios as: Three Basic Trigonometric Ratios. sine θ =. cosine θ =. tangent θ =. Where θ is the measure of a reference angle measured in degrees. Very often we use the abbreviations for sine, cosine, and tangent ratios. sin θ =. cos θ =.
