Some trigonometry
... Specifically, the circles in the above figures are of unit radius. In the first figure, the blue segment is tangent to the circle at the point (1, 0). We define tan θ to be the distance from (1, 0) to the point where the blue tangent line intersects the ray making an angle θ with the x-axis. We defi ...
