The cos values are tabularly opposite to that of sin angles. This means that whichever value of sin (0 - x) degree is the same as the value of cos (90 - x) degree. To find the value of cos divide by 4 in the opposite order of sin, i.e., sequentially from 4, 3, 2, 1 and 0 by 4 and take the square root.
