In PostgreSQL, tan() is a mathematical function that returns the tangent of the input expression.
The input expression is provided as an argument, and it is specified in degrees.
In trigonometry, in a right-angled triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
Continue readingIn PostgreSQL, asin() is a mathematical function that returns the angle, in radians, whose sine is the specified expression.
In other words, it returns the arcsine of its argument.
The arcsine is typically used to find the measure of an angle when two sides of a right triangle are known.
The arcsine is the inverse of the sine function. To return the sine in Postgres, use sin() to specify the angle in radians, or sind() to specify it in degrees.
In PostgreSQL, asind() is a mathematical function that returns the angle, in degrees, whose sine is the specified expression.
In other words, it returns the arcsine of its argument.
The arcsine is typically used to find the measure of an angle when two sides of a right triangle are known.
The arcsine is the inverse of the sine function. To return the sine in Postgres, use sind() to specify the angle in degrees, or sin() to specify it in radians.
In PostgreSQL, sin() is a mathematical function that returns the trigonometric sine of the specified angle, as measured in radians.
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.
Continue readingIn 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, cosd() is a mathematical function that returns the trigonometric cosine of the specified angle, as measured in degrees.
You specify the angle by providing an argument to the function when calling it.

The inverse cosine is also known as the arccosine.
Continue readingIn PostgreSQL, acosd() is a mathematical function that returns the inverse cosine of the specified expression, measured in degrees.
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.
