The intermediate Value Theorem (IVT) is a fundamental theorem in calculus that guarantees the existence of a point where a continuous function takes on a given value between two given values.
The IVT has numerous applications in mathematics, including providing a rigorous proof for the existence of solutions to equations, determining if a function is continuous, and finding roots of functions.
In this article, we will explore the Intermediate Value Theorem and provide a stepbystep guide on how to use an online IVT calculator to find solutions to equations and determine the continuity of functions.
In this section, we will provide a detailed explanation of the Intermediate Value Theorem, its mathematical formulation, and its geometrical interpretation. We will also discuss some important applications of the IVT, including its use in proving the existence of solutions to equations and determining the continuity of functions.

Finds Solutions to Equations
The intermediate value theorem (IVT) states that if a function is continuous on a closed interval, then for any value between the function’s minimum and maximum values, there exists at least one value of the independent variable at which the function takes on that intermediate value.
The IVT calculator uses this theorem to find solutions to equations by first checking if the function is continuous on the given interval. If it is, the calculator then uses a bisection method to repeatedly divide the interval in half until the desired accuracy is reached. At each step, the calculator evaluates the function at the midpoint of the current interval to determine if the function value is closer to the desired value than the previous step. If it is, the calculator continues to divide the interval in half in that direction. Otherwise, the calculator continues to divide the interval in half in the opposite direction.
This process continues until the interval is sufficiently small, at which point the calculator returns the midpoint of the final interval as the approximate solution to the equation.
Here are some examples of how the IVT calculator can be used to find solutions to equations:
 Example 1: Find the solution to the equation sin(x) = 0.5 on the interval [0, π].
 Example 2: Find all solutions to the equation x^3 – 2x – 5 = 0 on the interval [3, 3].
 Example 3: Find the root of the function f(x) = x^2 – 4 on the interval [1, 3].
The IVT calculator can be a valuable tool for finding solutions to equations, especially when the equations are complex or do not have a closedform solution.
The IVT calculator is easy to use and can save a lot of time and effort when solving equations. It is a valuable tool for students, researchers, and professionals who need to find solutions to equations quickly and easily.
Determines Continuity of Functions
The intermediate value theorem (IVT) can also be used to determine the continuity of functions. A function is continuous on an interval if it has no breaks or jumps in its graph. In other words, if you can draw the graph of the function without lifting your pen from the paper, then the function is continuous.
 Continuous Function: A function is continuous on an interval if, for any value in the interval, the limit of the function as the independent variable approaches that value is equal to the value of the function at that value.
 IVT Test for Continuity: The IVT can be used to determine if a function is continuous on an interval. If a function is continuous on a closed interval, then for any value between the function’s minimum and maximum values, there exists at least one value of the independent variable at which the function takes on that intermediate value.
 Using the IVT Calculator to Determine Continuity: The IVT calculator can be used to determine if a function is continuous on an interval by checking if the function takes on all values between its minimum and maximum values. If the calculator can find a value of the independent variable for each value between the function’s minimum and maximum values, then the function is continuous on that interval. Otherwise, the function is not continuous on that interval.

Examples:
 The function f(x) = x^2 is continuous on the interval [1, 1] because it takes on all values between its minimum value of 0 and its maximum value of 1.
 The function f(x) = 1/x is not continuous on the interval [0, 1] because it does not take on the value of 0.
The IVT calculator can be a valuable tool for determining the continuity of functions. It is easy to use and can save a lot of time and effort when analyzing the continuity of functions.
