To know what is the additive inverse of the polynomial, we solve for the polynomial that results from negating all of the terms in the original polynomial. In other words, the additive inverse of a polynomial is the polynomial that has the same coefficients as the original polynomial but with the opposite sign. Additive inverses […]

Is -2 a real number? The answer is yes; $-2$ is a real number. Real numbers are the numbers that we use in our everyday lives. They are the numbers that we use when we count or measure things. They are the numbers that we use when we add, subtract, multiply, and divide. The Real […]

Solving initial value problems (IVPs) is an important concept in differential equations. Like the unique key that opens a specific door, an initial condition can unlock a unique solution to a differential equation. As we dive into this article, we aim to unravel the mysterious process of solving initial value problems in differential equations. This […]

What is 2i? It is an imaginary number because 2i has the form $bi$, where $b$ is a real number, and $i$ is the imaginary unit. These numbers give a value for the square root of negative numbers. Note that the square root of a negative number does not exist in the real line. Let […]

Inverse variation means that a variable has an inverse relationship with another variable, i.e., the two quantities are inversely proportional or varies inversely to each other. Mathematically, it is defined by the relation $y = dfrac{c}{x}$, where $x$ and $y$ are two variables and $c$ is a constant. Two quantities $x$ and $y$ are said […]
