What is sin mean in math?

In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.

How is sin calculated?

In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H).

What sine means?

1: the trigonometric function that for an acute angle is the ratio between the leg opposite the angle when it is considered part of a right triangle and the hypotenuse.

Is horizontal cos or sin?

The component of a vector along any direction is the magnitude of the vector multiplied by the cosine of the angle between the vector and the line. The horizontal component of the vector F shown in Figure 1 is F cos (A) while Figure 2 shows the components of a vector in two perpendicular directions.

Why Sine is called sine?
