 In this video, we provide the solution to question number eight for the practice exam number one for math 1060 We're given a point P on the unit circle whose coordinates are x point eight four eight and y point five three zero So it's important to notice this is a point on the unit circle Suppose that theta is the angle in standard position and terminates with the point P We want to then compute sine Theta of that angle right there So the thing to remember here is with the unit circle if we have our picture it would look something like this Here's our point P. Here's our theta right here points on the unit circle coincide With these trigonometric ratios here So if you have this point x comma y on the unit circle that x coordinate will be cosine of theta And the y coordinate will be sine of theta. So if we're looking for A sine of theta right here, that just means we're looking for the associated y Coordinate on the unit circle, which is point five three zero So we then would select choice F as the correct answer
