## What is Runge Kutta 4th order method?

The most commonly used method is Runge-Kutta fourth order method. x(1) = 1, using the Runge-Kutta second order and fourth order with step size of h = 1. yi+1 = yi + h 2 (k1 + k2), where k1 = f(xi,ti), k2 = f(xi + h, ti + hk1).

### What is Picard method?

The Picard’s method is an iterative method and is primarily used for approximating solutions to differential equations.

#### What are the disadvantages of Euler’s method?

The Euler method is only first order convergent, i.e., the error of the computed solution is O(h), where h is the time step. This is unacceptably poor, and requires a too small step size to achieve some serious accuracy.

**What do you mean by numerical solution of differential equations?**

Numerical methods for ordinary differential equations are methods used to find numerical approximations to the solutions of ordinary differential equations (ODEs). Their use is also known as “numerical integration”, although this term can also refer to the computation of integrals.

**What is Picard’s method?**

The Picard’s iterative method gives a sequence of approximations Y1(x), Y2(x), … Yk(x) to the solution of differential equations such that the nth approximation is obtained from one or more previous approximations.

## What is Runge-Kutta 2nd order?

Given the following inputs: An ordinary differential equation that defines the value of dy/dx in the form x and y. Initial value of y, i.e., y(0).

### What is Taylor’s method?

In mathematics, the Taylor series of a function is an infinite sum of terms that are expressed in terms of the function’s derivatives at a single point. For most common functions, the function and the sum of its Taylor series are equal near this point.

#### Is Euler’s method accurate?

Euler’s Method will only be accurate over small increments and as long as our function does not change too rapidly. Consequently, we need to ensure that our step-size isn’t too large or our numerical solution will be inaccurate.
