WebThe law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles. The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. In the example in the video, the angle between the two sides is NOT 90 degrees; it's 87. WebInstead, you will be expected to memorize the sines and cosines of some special angles. Other than that, either you will be allowed to use a calculator or you'll be given the values. The actual computation for cosine (angles expressed with radians, not degrees): cos x = ½ [ e^ (-i*x) + e^ (i*x)]

WebWell, finding angles is another major use of trigonometry. For example, if you know that the ratio between two sides is 1 to 2, and the sides happen to be opposite and hypotenuse to an unknown angle A, then you can use the sine ratio to tell you that sin A = 1/2. When an angle is equal to 30 degrees, then the sine ratio is always 1/2.
