The growth of functions in numerical methods refers to how the computational complexity and resource requirements of algorithms increase with the size of the input data or the number of computations. As problems become larger or more complex, the efficiency of numerical methods can significantly impact performance, often described using big O notation. Understanding this growth is crucial for selecting appropriate algorithms for tasks such as solving equations, optimization, or simulations in various scientific and engineering applications. Efficient numerical methods can mitigate potential pitfalls like excessive computation time and memory usage.
For some functions the answer is relatively straightforward and you have a formula. For other functions, it may be possible, using numerical methods, to calculate the area under the function's curve. This will be a numerical answer to the problem under specific boundary conditions.
Numerical methods are used to find solutions to problems when purely analytical methods fail.
Numerical Analysis - an area of mathematics that uses various numerical methods to find numerical approximations to mathematical problems, while also analysing those methods to see if there is any way to reduce the numerical error involved in using them, thus resulting in more reliable numerical methods that give more accurate approximations than previously.
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.

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.

when an operator operate on a function and same function is reproduced with some numerical value then the function is called eigenfunction and the numerical value is called eigen value.
Numerical data is data measured or identified on a numerical scale. Numerical can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms, and graphs.
