Question

1) Find the values of the trigonometric functions of θ from the information given.

cot(θ) = − 3/5, cos(θ) > 0

sin(θ)

=

cos(θ)

=

tan(θ)

=

csc(θ)

=

sec(θ)

=

2)

The point P is on the unit circle. Find P(x, y) from the given information.

The x-coordinate of P is −√5/4, and P lies below the x-axis.

P(x, y) = ( )

3) Find the terminal point P(x, y)  on the unit circle determined by the given value of t.

t = − 2pi/3

P(x, y) = (   )

4) Consider the following.

t =

10π
