The other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3

Cosine of angles

Generally, given cos (x), the value that is similar to cos x will be sum of the angle and multiple of 360.

Hence for the angle cos(∏/3), the angles similar to this angle will be expressed as:

Cos(2∏n + ∏/3) where:

  • n is any positive integer.

The other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3
