In PostgreSQL, cos() is a mathematical function that returns the trigonometric cosine of the specified angle, as measured in radians.
You specify the angle by providing an argument to the function when calling it.

In PostgreSQL, ln() is a mathematical function that returns the natural logarithm of its argument.
How the Exp() Function Works in PostgreSQL
In PostgreSQL, exp() is a mathematical function that returns the exponential value of its argument.
How Pi() Works in PostgreSQL
In PostgreSQL, the pi() function returns the number π.
π constant is a mathematical constant. It is defined as the ratio of a circle’s circumference to its diameter.
Continue readingHow the Degrees() Function Works in PostgreSQL
In 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 (2π).
