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 .

What is the exact value of tan 0?

The exact value of tan(0) is 0 .
