Finding the exact center of a circle
WebJul 12, 2024 · Example 5.3.1. The point (3, 4) is on the circle of radius 5 at some angle θ. Find cos(θ) and sin(θ). Solution. Knowing the radius of the circle and coordinates of the point, we can evaluate the cosine and sine functions as the ratio of the sides. cos(θ) = x r = 3 5sin(θ) = y r = 4 5.
