For the sine function, we can handle other values.

The sine function is no longer bounded if it is defined over the set of all complex numbers.

It should not be confused with the trigonometric sine function.

It is essentially equivalent to a table of values of the sine function.

An equation involving sine functions and tetrahedra is as follows.

This is still quick to compute, and much more accurate for smooth functions such as the sine function.

The figure shows how the sign of the sine function varies as the angle changes quadrant.

Since a sine function cannot be greater than 1, there is no critical angle.

Think of the wave as a sine function.

Enough data points for a mathematical sine function are stored in digital memory.
