### What is d/dx? A Detailed Explanation

The symbol d/dx is used to differentiate any function with respect to the variable $x$. The derivative or differentiation in mathematics is used to determine the rate of change of a given function. So, if we are using the d/dx formula or the d/dx symbol with a function “$f$,” then we are calculating the rate […]

### What Is the Integral of Arctan x And What Are Its Applications?

The integral of $arctan x$ or the inverse of tan x is the function that returns the inverse tangent of x as its derivative. It is equal to: $int arctan xphantom{x}dx= x arctan x -dfrac{1}{2} ln|1 + x^2| + C$. In this complete guide, learn how to derive the formula for arctan x and how […]

### How Hard is Calculus?

Calculus is not that hard if you have a good understanding of its prerequisites, such as algebra and pre-calculus. The name calculus sends a shiver down the spine of many students. Is the subject of calculus really this hard? Basic calculus is not that hard, but if a student has a lax attitude or behaviour […]

### Coefficient Matrix – Explanation & Examples

A matrix that consists of the coefficients of a linear equation is known as a coefficient matrix. The coefficient matrix solves linear systems or linear algebra problems involving linear expressions. In the study of matrices, the coefficient matrix is used for arithmetic operations on matrices. A method like Cramer’s rule utilizes coefficient matrices to find […]

### Function Operations – Explanation & Examples

Function operations are the arithmetic operations that are used to solve a function. The arithmetic operations applied to a function are addition, subtraction, multiplication, and division. In this topic, we will learn about functions and how we can apply different operations to functions. What Is a Function? A function is used to show a relation […]
