The trigonometry illustrates that the four angles whose cosine is the same as cos pi/3 will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3
<h3>How to illustrate the information?</h3>
From the information, given cos (x), the value that is similar to cos x will be the sum of the angle and multiple of 360.
Therefore, for the angle cos(∏/3), the angles that are similar to this angle will be expressed as Cos(2∏n + ∏/3) where n is any positive integer.
Then the other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3. Also, the statement that all angles that have the same cosine will have the same sine is false. The sine of an angle is simply equal to the cosine of the complementary angle.

The additive inverse is zero. The addtive inverse property states that any number added or subtracted to zero give the same number.
Examples:
0 + 3 = 3
1 - 0 = 1
-8 + 0 = -8
-3 - 0 = -3
0 + (-1) = -1
