The main disadvantage of the bisection method for finding the root of an equation is that, compared to methods like the Newton-Raphson method and the Secant method, it requires a lot of work and a lot of iterations to get an answer with very small error, whilst a quarter of the same amount of work on the N-R method would give an answer with an error just as small.
In other words compared to other methods, the bisection method takes a long time to get to a decent answer and this is it's biggest disadvantage.

Which is the best method to find a root in numerical method?
The best method for finding a root in numerical methods often depends on the specific problem and its characteristics. The Newton-Raphson method is widely regarded for its rapid convergence, especially when the function is well-behaved and the initial guess is close to the actual root. However, if the function has multiple roots or is not differentiable, methods like the bisection method or the secant method may be more robust. Ultimately, the choice of method should consider factors such as convergence speed, ease of implementation, and the nature of the function.
Numerical method for solving can eqution bisection method?
A root-finding algorithm is a numerical method, or algorithm, for finding a value. Finding a root of f(x) − g(x) = 0 is the same as solving the equation f(x) = g(x).
How do you solve a nonlinear equation?
To solve a nonlinear equation, you can use various methods depending on the equation's characteristics. Common techniques include graphing, where you visualize the function to identify intersection points with the x-axis; numerical methods like the Newton-Raphson method or bisection method for finding approximate solutions; and algebraic methods such as factoring or substitution if applicable. In cases where explicit solutions are difficult to find, software tools or calculators can also be employed for numerical solutions.
What is indirect method in numerical analysis?
The indirect method in numerical analysis refers to techniques that solve mathematical problems by approximating solutions through iterative processes, rather than directly calculating them. This approach is often used for solving equations, optimization problems, or numerical integration, where an explicit formula may not be available. Examples include methods like Newton's method or the bisection method for root-finding. These methods typically involve making an initial guess and refining that guess through successive iterations until a desired level of accuracy is achieved.
What are the applications of numerical method?
Numerical methods are used to find solutions to problems when purely analytical methods fail.

How do you know which Numerical Method to use for which problem?
To know which numerical method to use for a problem one first needs to understand the various methods and evaluate the problems.
How can you find the minimum of a function?
There are to classes of methods to find the minimum of a function: analytical and numerical. Analytical methods are precise but cannot be applied always. For example, we can find the minimum of a function by setting its first derivative to zero and solve for the variable and then check the second derivative (must be positive). Numerical methods involve the application of steps repeatedly until an acceptable estimate of the solution is found. Numerical methods include Newton method, steepest descent method, golden section method, Simplex method, to name just a few.
Can you say that an iterative methods to solve a non-linear equation is actually a numerical method?
Yes, you can. Any iterative method/algorithm that is used to solve a continuous mathematics problem can also be called a numerical method/algorithm.
What is advantages of bisection method?
In the absence of other information, it is the most efficient.
What are the Merits of bisection methods?
The bisection method is a reliable root-finding technique that guarantees convergence to a root within a specified interval, provided that the function changes sign over that interval. Its simplicity and ease of implementation make it accessible for various applications. Additionally, the method provides a systematic way to narrow down the root's location, allowing for controlled precision in the solution. However, it may be slower than other methods, such as Newton's method, especially for functions with multiple roots or high complexity.
What is numerical method and what kinds are?
Numerical methods are mathematical techniques used to approximate solutions to problems that cannot be solved analytically. They are essential in various fields such as engineering, physics, and finance. Common types of numerical methods include interpolation, numerical integration, numerical differentiation, and solving ordinary and partial differential equations. These methods allow for the analysis and simulation of complex systems where exact solutions are impractical.
