Starting from 0° and progressing through 90°, cos⁡ (0°)=1=. The subsequent values, cos (30°), cos (45°), cos (60°), and cos (90°) follow a pattern such that, using the value of cos (0°) as a reference, to find the values of cosine for the subsequent angles, we simply decrease the number under the radical sign in the nu See more
