Tutorial for using the unit circle to evaluate for tangent when angle is greater than

The video tutorial explains the concept of tangent 675 and its relation to the unit circle. It introduces coterminal angles, showing how angles greater than 360 degrees can be simplified. The tutorial demonstrates calculating the tangent of 315 degrees by using reflections and coterminal angles, emphasizing the simplification of angle calculations.

What is the significance of an angle being greater than 360 degrees in trigonometry?

• It suggests the angle is negative.

• It shows the angle is less than a right angle.

• It means the angle is invalid.

• It indicates a full rotation and starts a new cycle.

What is a coterminal angle?

• An angle that is always less than 90 degrees.

• An angle that shares the same initial and terminal sides as another angle.

• An angle that is always greater than 180 degrees.

• An angle that is only used in calculus.

How can you simplify the calculation of tangent 675?

• By using the tangent of 0 degrees.

• By using the tangent of 360 degrees.

• By using the tangent of 315 degrees.

• By using the tangent of 90 degrees.
