is sin the x or y value on unit circle - Axtarish в Google
Because the sine value is the y-coordinate on the unit circle, the other angle with the same sine will share the same y-value, but have the opposite x-value.

Trigonometric Functions: Unit Circle ; Sine, sin θ = y, Cosecant, csc θ = 1y ; Cosine, cos θ = x, Secant, sec θ = 1x.
The unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
Because the sine value is the y-coordinate on the unit circle, the other angle with the same sine will share the same y-value, but have the opposite x-value.
So the sine is the y-coordinate. The trigonometric ratio defining the tangent (opposite over adjacent) may be less intuitive from the unit circle, but I hope ...
The value of sin θ is the y-coördinate of the endpoint of the unit radius. The value of cos θ is the x-coördinate. The following shows the coördinates of the ...
