MySQL ATAN() Function – Return the Arc Tangent of a Value (or Values)
In MySQL, the ATAN() function returns the arc tangent of a value. It can also be used to return the arc tangent of two values.
You provide the value/s as an argument when calling the function.
MySQL ASIN() Function – Return the Arc Sine of a Number
In MySQL, the ASIN() function returns the arc sine of a number.
You provide the number as an argument when calling the function.
MySQL ACOS() Function – Return the Arc Cosine of a Number
In MySQL, the ACOS() function returns the arc cosine of a number.
You provide the number as an argument when calling the function.
MySQL RADIANS() Function – Convert From Degrees to Radians
In MySQL, the RADIANS() function converts a value from degrees to radians, and returns the result.
You provide the value in degrees as an argument when calling the function.
MySQL DEGREES() Function – Convert From Radians to Degrees
In MySQL, the DEGREES() function converts a value from radians to degrees, and returns the result.
You provide the radian value as an argument when calling the function.
MySQL CRC32() Function – Examples
In MySQL, the CRC32() function computes a cyclic redundancy check value and returns a 32-bit unsigned value.
CRC stands for Cyclic Redundancy Check. A CRC is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data (although, it doesn’t necessarily guard against malicious or intentional changes).
MySQL COT() Function – Return the Cotangent of a Number in MySQL
In MySQL, the COT() function returns the cotangent of a given value.
You provide the value as an argument when calling the function.
MySQL COS() Function – Return the Cosine of a Number in MySQL
In MySQL, the COS() function returns the cosine of a given value, where the value is given in radians.
The cosine is the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
MySQL ABS() Function – Return the Absolute Value of a Number
In MySQL, the ABS() function returns the absolute value of a given value.
An absolute value is the distance of a number on the number line from 0 without considering which direction from zero the number lies. Therefore, the absolute value of a number is always a non-negative value (i.e. it’s never negative).
