Question: On the following unit circle, θ is in radians.Without a calculator, evaluate the following expressions to the nearest hundredth.\table [ [Expression Value], [cos (π+θ)
Question: Below is a blank unit circle. For this question, your job is to input each angle (in radians) of the unit circle next to the corresponding terminal angle.
Step 1 The terminal point (x, y) on the unit circle determine by 0 radians needs to be determined.
Here’s how to approach this question Use the unit circle equation x 2 + y 2 = 1 and the given angle π 6 radians to find the coordinates of the point, noting that cos (π 6) and sin (π 6) will provide the x and y.

Question: Find the terminal point on the unit circle determined by (3pi)/ (4) radians. Use exact values, not decimal approximations.
Here’s how to approach this question For the first part of the problem, identify the key angles on the unit circle in both degrees and radians.
On the unit circle, sketch θ=2.90π radians in standard position. Then use the coordinates shown, which are rounded to the hundredths place, to find csc(2.90π) and tan(2.90π).
In the context of unraveling the unit circle, the sine function creates a relationship between the vertical distance and the y-axis starting at 0 radians going counter-clockwise.
