    Introduction to Bisection Method Calculator

    The bisection method calculator is an online tool that finds a root function using the bisection method, or interval method.

    bisection method calculator

    Our bisect calculator determines the mid-value or bisection problems and checks the error of convergence in less than a minute.For educational purposes or deeper understanding, our calculator offer a step-by-step solution, showing each iteration of the bisection method and how the interval is refined to converge to the root.

    the Bisection Method Calculator is a valuable tool for anyone needing to find the roots of a function quickly and accurately. Additionally, in calculus, when faced with indeterminate forms in limits, our L'Hôpital's Rule is a powerful tool used to evaluate limits involving functions that approach zero over zero or infinity over infinity. The l'hospital's rule calculator provides a convenient way to apply this rule and obtain precise solutions to limit problems, making it an essential tool for calculus students and professionals alike.

    What is the Bisection Method?

    The bisection method is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie to move for the next steps until the current root and previous root do not get the same value.

    This method is useful for the nonlinearity of the function as it is a robust method that it handles lengthy numerical problems.

    Related:For numerical approximation of solutions to ordinary differential equations, you can utilize our euler's formula calculator. Euler's Method, a simple yet effective numerical procedure, provides approximate solutions to differential equations by iteratively stepping through the solution curve in small increments. By utilizing this calculator, you can efficiently compute numerical solutions to a wide range of differential equations, aiding in engineering, physics, and mathematical modeling.

    Formula Used by Bisect Calculator

    The bisection method formula is based on two root values that give a solution of the mid value using the mean formula. The bisection method calculator mainly uses the following formula which is given,

    $$ C \;=\; \frac{(a+b)}{2} $$

    This formula calculates the midpoint C between two given values a and b. In the context of the bisection method, a and b represent two endpoints of an interval where a function changes sign, indicating the presence of a root between them.


    • a and b are the endpoints of the interval.
    • C represents the midpoint between a and b.
    • The formula calculates the midpoint by taking the arithmetic mean of a and b, which is then used to refine the search for the root.

    Additionally, When dealing with the differentiation of functions involving quotients, the quotient derivative calculator can be immensely helpful. The Quotient Rule is another fundamental rule of differentiation used to find the derivative of a quotient of two functions. By using this calculator, you can efficiently compute the derivative of quotient functions without the need for manual calculations.

    Working Mechanism of Bisection Calculator

    The Bisection Method Online Calculator uses a straightforward method as per the formula of the mid-value problem so that you always get the correct result when you use our tool for the calculation of numerical problems.

    When you enter the input value in the calculator to solve the bisection method problems, it will analyze the given input whether the given data is given the solution or not. After identification follow the below steps so that you clearly understand the workings of the calculator.

    It adds the first root in the given function and the second root in the given function so that you get the values in the form of f(a) > 0 and f(b) < 0. If its value does not match with this condition f(a) > 0 and f(b) < 0 then it supposes another value c then added into the given equation so that the given condition is followed.

    The bisect calculator calculates a midpoint c using the arithmetic mean between a and b as c = (a + b) / 2. Then it evaluates the function f for the value of c.

    The next root of the function is found only if the value of f(c) = 0. If (c) ≠ 0, then we need to check the sign (negative or positive). if f(c) has the same sign as f(b) has. To get the right value with a different sign and get the new value of a or b then again it follows the previous step.

    In this way, our tool repeats this process again and again after you get the same value as the previous mid-value. Further, When it comes to solving differential equations numerically, tools like the heun method calculator can be invaluable. The Improved Euler Method, also known as Heun's Method, is a numerical procedure for approximating the solution of ordinary differential equations. By using this calculator, you can quickly and accurately compute numerical solutions to a wide range of differential equations.

    Let's understand an example along with a solution of the bisection method to see the bisection method calculator working mechanism.

    Solved Example of Bisection Problem

    The bisection calculator gives you the solution of the bisection method problem in a step-by-step process. You should also be wondering how to do bisection method manually. So, here’s an example for that,


    Determine the root of the following equation within the interval [2,3].

    $$ f(x) \;=\; x^3 - 2x - 5 $$


    Evaluate f(a) and f(b):

    $$ f(2) \;=\; (2)^3 - 2(2) - 5 \;=\; 1 $$

    $$ f(3) \;=\; (3)^3 - 2(3) - 5 \;=\; 11 $$

    As, f(a) = 1 and f(b) have opposite signs, so we will proceed with the bisection method,

    First of all, we will calculate the midpoint:

    $$ c \;=\; \frac{(a+b)}{2} \;=\; \frac{(2+3)}{2} \;=\; 2.5 $$

    Evaluate f(c):

    $$ f(2.5) \;=\; (2.5)^3 - 2(2.5) - 5 \;=\; -0.375 $$

    As f(a) and f(c) have opposite signs, hence we will update b=2.5 and calculate the midpoint of updated interval:

    $$ c \;=\; \frac{(2+2.5)}{2} \;=\; 2.25 $$

    Evaluating f(c):

    $$ f(2.25) \;=\; (2.25)^3 - 2(2.25) - 5 \;=\; -0.6094 $$

    As f(a) and f(c) still have opposite signs, so we will update a=2.25 and continue the process until we reach the desired level of accuracy.

    Continue the process iteratively until the width of the interval is smaller than the desired tolerance, or until the function value at the midpoint is sufficiently close to zero. By following these steps iteratively, you can approximate the root of the equation within the specified interval manually.

    Additionally, in calculus, when dealing with the differentiation of products of functions, the product rule derivative calculator is an invaluable tool. The Product Rule is a fundamental rule of differentiation used to find the derivative of a product of two functions.
