Is there any way of solving [tex]\int_{0}^{1} \frac{1}{\sqrt{100-x^5}} dx[/tex] by some regular method? If not, how does one go about solving such integrals numerically?
Ahh so it's going to be like that is it, well in that case, to 2000 sf:dextercioby said:P.S.Here are 125 sig.digs.

The accuracy of a numerical integration method can be determined by comparing the results with the exact solution, if available. Additionally, the error can be calculated by using a known function with an exact solution and comparing the difference between the exact and numerical results.
The main steps in solving an integral numerically include: choosing an appropriate numerical integration method, determining the limits of integration, dividing the integral into smaller subintervals, calculating the function values at each subinterval, and finally, summing up the results to approximate the integral.
Numerical integration allows for the solution of integrals that cannot be solved analytically or are too complex to solve by hand. It also provides a more accurate solution compared to approximations used in analytical integration methods.
The choice of numerical integration method depends on the type of integral (e.g. definite or indefinite), the function being integrated, and the desired level of accuracy. Some common methods include the trapezoidal rule, Simpson's rule, and Gaussian quadrature.
Yes, numerical integration can be used for any type of function, including trigonometric, exponential, and logarithmic functions. However, the accuracy of the results may vary depending on the complexity of the function and the chosen numerical integration method.
