The calculator tool used for finding the co-terminal of an angle is called as co-terminal calculator. The meaning of co-terminal angles is when two angles are drawn on an axis in standard position and they have a common terminal side. A given angle usually can have both positive and negative angles as its co-terminal angles.
Example 1: Give two positive and negative co-terminal values for the angle 30?
First, find the positive co-terminal angle of 30.
Add 360 to 30 that is, 30 + 360 = 390.
Add 720 to 30 that is 30 + 720 = 750.
The multiples of 360 are subtracted from 30 to find the negative co-terminal angles.
Subtract 360 from 30 that is, 30 - 360= -330.
Subtract 720 from 30 that is 30 - 720 = -690.
Therefore the co-terminal angles of 30 are 390, 750, -330, and -690.
Example 2: Give two positive and negative co-terminal values for the angle 45?
First, find the positive co-terminal angle of 45.
Add 360 to 45 that is, 45 + 360 = 405.
Add 720 to 45 that is 45 + 720 = 765.
The multiples of 360 are subtracted from 30 to find the negative co-terminal angles.
Subtract 360 from 45 that is, 45 - 360= -315.
Subtract 720 from 45 that is 45 - 720 = -675.
Therefore the co-terminal angles of 30 are 405, 765, -315, and 675.
