What is sin 0?

The sine function (sin) is a trigonometric function that relates the measure of an angle to the ratio of the length of the side opposite that angle to the length of the hypotenuse in a right triangle.

When the angle is 0 degrees (or 0 radians), the sine of 0 is 0. This means that in a right triangle with a 0-degree angle, the side opposite to the angle has a length of 0, resulting in a ratio of 0 to the hypotenuse.

Graphically, the sine function creates a wave-like pattern and has a value of 0 at every multiple of 180 degrees (or π radians). Hence, sin 0 is 0, as it falls at the 0-degree angle.

The values of the sine function oscillate between -1 and 1 for different angles, reaching a maximum of 1 at 90 degrees (π/2 radians) and a minimum of -1 at 270 degrees (3π/2 radians).
