Use the unit circle to find the value of tan (225 degrees

The value of tan 225 degrees using the unit circles is 1

Given the trigonometry function tan 225 degrees, this can also be written as;

tan 225 = tan(180 + 45)

This shows that the tangent function falls in the third quadrant. In the third quadrant;

The expression above then becomes

Hence the value of tan 225 degrees using the unit circles is 1
