What is the relationship between the unit circle and the trigonometric functions?

• Trigonometric functions are only applicable to squares, not circles

• The unit circle has no relationship with trigonometric functions

• The unit circle is used to calculate algebraic functions, not trigonometric functions

• The unit circle provides a visual representation of the values of trigonometric functions for different angles.

How is the unit circle used to find trigonometric values?

• By using the coordinates of points on the circle to determine the sine, cosine, and tangent of angles.

• By using the radius to calculate the area of the circle

• By measuring the circumference of the circle

• By counting the number of points on the circle

Using the unit circle, explain how you can find the value of tangent of an angle both visually and algebraically. Use pi/4 as an example.
