In MySQL, the SIN() function returns the sine of a given value, where the value is given in radians.
The sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
In MySQL, the SIGN() function returns the sign of a number. That is, it indicates whether or not the value is a positive number, a negative number, or zero.
You provide the value as an argument when calling the function.
The function returns the following result, depending on whether the argument is positive, negative, or zero.
