(1.) You can determine the value of cos 15° without using a calculator is by using the Half-Angle Formula for the cosine function. The Half-Angle Formula for the cosine function is: cos (A/2) = ±√[(1 + cos A)/2], where, for this problem, A = 30°. 2007-10-24 · Details. The underlying functions newsine and newcosine work by breaking a given angle down into multiples of 90, 30, 15, 3, and 1 degree(s). The values at 3 degrees were found using combinations of 15 and 72 degrees, and the values at 1 degree by using the sine and cosine triple angle formulas and solving the resultant cubics.
