The ATAN2() function in SQLite calculates the arc tangent (inverse tangent) of the ratio of two given numeric values, typically representing the y-coordinate and x-coordinate of a point.
Unlike ATAN(), which calculates the angle based only on a single tangent value, ATAN2() considers both the x and y values to determine the correct quadrant for the resulting angle.
The ATAN() function in SQLite calculates the arc tangent (inverse tangent) of a given numeric value. The result is the angle in radians whose tangent is the specified number.
SQLite provides various mathematical functions out of the box, and one of them is the power() function (also available as pow()).
The power() function calculates the result of raising one number to the power of another. In other words, it performs an exponentiation operation. This function is particularly useful for mathematical operations where powers or exponents are required.
The ATANH() function in SQLite calculates the inverse hyperbolic tangent of a given numeric value. The result is the value whose hyperbolic tangent is the specified number.
The exp() function in SQLite calculates the exponential of a given number, where the base is the mathematical constant e (approximately 2.71828). In other words, it returns e raised to the power of x for a given input x.
This function can be useful in scientific and statistical calculations involving exponential growth, decay, and other natural logarithmic-based transformations.

This function is helpful in mathematical calculations involving growth rates, exponential functions, and natural logarithmic transformations.
Continue readingSQLite is a popular, lightweight, SQL-based relational database engine, frequently used in applications where a full database management system isn’t necessary. Among its various features, SQLite offers built-in functions to track the number of changes made to the database during operations, and one of these functions is total_changes().
In this article, we’ll discuss what the total_changes() function does, how it can be used, and provide examples to illustrate its functionality.
In SQLite, the degrees() function is used to convert an angle from radians to degrees. In trigonometry, angles are commonly measured in either radians or degrees, and this function helps to easily switch from one unit to the other.
In SQLite, the SIN() function calculates the sine of an angle specified in radians.
This is a fundamental trigonometric function that returns a value between -1 and 1, representing the ratio of the opposite side to the hypotenuse in a right triangle.
Continue readingThe log2() function in SQLite calculates the base-2 logarithm of a given number.
This function can be useful for scenarios such as binary calculations, information theory, or situations where the base-2 logarithm is needed.
