The ACOSH() function in SQLite calculates the inverse hyperbolic cosine of a given number. The inverse hyperbolic cosine of a number is the value whose hyperbolic cosine equals that number.

Understanding SQLite’s COSH() Function
The COSH() function in SQLite calculates the hyperbolic cosine of a number, which is similar to the regular cosine function, but for hyperbolic geometry.
An Introduction to Strict Tables in SQLite
SQLite is widely known for its simplicity, flexibility, and lightweight architecture. One feature that sets it apart from most other SQL databases is its dynamic typing system, which allows columns in a table to store data of any type, regardless of their declared type.
While some developers welcome this departure from the traditional SQL approach, others find it extremely problematic, due to its non-enforcement of data types, which could potentially lead to data integrity issues.
Understanding the SQRT() Function in SQLite
In SQLite, the SQRT() function calculates the square root of a number. It returns the value which, when multiplied by itself, equals the input number.
Note that SQLite returns NULL if you try to calculate the square root of a negative number, NULL, or a value of the wrong type.
A Quick Look at SQLite’s ASINH() Function
The ASINH() function in SQLite calculates the inverse hyperbolic sine of a given numeric value. The result is the value whose hyperbolic sine is the specified number.
Understanding SQLite’s PI() Function
The PI() function in SQLite returns the mathematical constant π (pi), which is approximately 3.14159265358979. It is used to represent the ratio of the circumference of a circle to its diameter.
The PI() function is commonly employed in mathematical computations, particularly in geometry, trigonometry, and other scientific calculations involving circles and angles.
Overview of the SQLite COS() Function
The COS() function in SQLite calculates the cosine of a given angle. The angle must be specified in radians. The result is the cosine of the angle, which is a real number between -1 and 1.
Understanding SQLite’s MOD() Function
The MOD() function in SQLite is used to calculate the remainder when one number is divided by another. This operation is commonly known as the modulo operation.
Understanding Serverless Databases: Classic Serverless vs Neo-Serverless
The term “serverless database” has gained popularity with the rise of cloud computing and on-demand services, but it has a dual meaning depending on context.
In particular, databases can be “serverless” in either the traditional, client-side manner (e.g., SQLite’s model) or the cloud-native way often associated with managed databases.
This article explores these two approaches to serverless databases—classic serverless and neo-serverless—along with contrasting examples from other database models like client/server architectures.
An Overview of the SINH() Function in SQLite
The SINH() function in SQLite calculates the hyperbolic sine of a value. The hyperbolic sine is a mathematical function that can return any real number and grows exponentially as its input increases or decreases.
