WebJan 13, 2024 · π 4. Go ahead and pause the video and see what you can come up with. Let’s check your answers. The cos 180 ∘ = − 1, because at 180 °, the ray hits the circle at the point ( − 1, 0). The sin 2 π 3 = 3 2, because it hits at the point ( − 1 2, 3 2). And the tan π 4 = 1 because the ray hits the circle at the point ( 2, 2). And 2 2 = 1. WebNov 15, 2024 · I suggest trying a simple example, such as the ellipse generated by these parameterized equations: x = 2 cos ( θ) + 5, y = sin ( θ) + 2. Plot these points for a few dozen equally-spaced of θ ranging from 0 to 2 π, confirm that you get an ellipse, then give these sets of coordinates to your function and see if it gives you back a circle.
