Where is 0 on the unit circle?

Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.

Subsequently, one may also ask, where on the unit circle is sin 0?

Unit Circle — Radians We know that the cosine is equal to the x-coordinate, and the sine is equal to the y-coordinate, so we can write this: cos 0 ° = 1. sin 0 ° = 0.

Likewise, where did the unit circle originate? Where the center of the circle is the origin on a graph. The unit circle and trigonometry date back to the 2nd millennium BC to Egyptian mathematics and Babylonian mathematics.

Consequently, what is the sin at 0?

On the unit circle, the x-coordinate at each position is the cosine of the given angle, and the y-coordinate is the sine. For θ=0 , the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0)=0 .
