Question

he unit circle is shown below. Complete the following. (a) Sketch $\theta = 45^\circ$ in standard position on the unit circle. Find the lengths of the legs of its reference triangle. These are labeled a and b in the figure below, when an angle is sketched. Then use your reference triangle to find the coordinates of point P. Use exact values and not decimal approximations. a= b= P = (\square, \square)

Step 1

In standard position, the angle is measured counterclockwise from the positive x-axis, and the point P lies on the unit circle. A 45° angle places P in the first quadrant. Show more…
