Trigonometry Examples. Split 75 75 into two angles where the values of the six trigonometric functions are known. Apply the sum of angles identity cos(x+y) = cos(x)cos(y)−sin(x)sin(y) cos ( x + y) = cos ( x) cos ( y) - sin ( x) sin ( y). The exact value of cos(30) cos ( 30) is √3 2 3 2. The exact value of cos(45) cos ( 45) is √2 2 2 2.

We know that: cosx + cosy = 2cos(x+y)/2 * cos(x-y)/2. Then : cos75+cos15= 2 cos(75+15)/2 * cos(75-15)/2 = 2cos(90/2) * cos(60/2) = 2cos(45)*cos(30) = 2(sqrt2)/2.

To find the value of cos 75 degrees using the unit circle: Rotate 'r' anticlockwise to form 75° angle with the positive x-axis. The cos of 75 degrees equals the x-coordinate (0.2588) of the point of intersection (0.2588, 0.9659) of unit circle and r. Hence the value of cos 75° = x = 0.2588 (approx)

Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical.
