In PostgreSQL, sind() is a mathematical function that returns the trigonometric sine of the specified angle, as measured in degrees.
You specify the angle by providing an argument to the function when calling it.
In trigonometry, sine is the function that is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse.

You specify the angle by providing an argument to the function when calling it.
Continue readingIn PostgreSQL, acos() is a mathematical function that returns the inverse cosine of the specified expression, measured in radians.
The inverse cosine is also known as the arccosine.

The inverse cosine is also known as the arccosine.
Continue readingIn PostgreSQL, log() is a mathematical function that returns the base 10 logarithm of its argument.
However, it also allows you to optionally specify a base with which to use.
Continue readingIn PostgreSQL, ln() is a mathematical function that returns the natural logarithm of its argument.
In PostgreSQL, exp() is a mathematical function that returns the exponential value of its argument.
In PostgreSQL, the pi() function returns the number π.
Ï€ constant is a mathematical constant. It is defined as the ratio of a circle’s circumference to its diameter.
Continue readingIn PostgreSQL, the degrees() function converts from radians to degrees.
The radian is the SI (International System of Units) unit for measuring angles. One radian is just under 57.3 degrees, and a full circle has just over 6.28 radians (2Ï€).
