Numerical integration matlab

Integration deals with two essentially different types of problems.

• In the first type, derivative of a function is given and we want to find the function.

• Indefinite integral matlab
• Trapz matlab
• Double integral matlab
• Definite integral matlab

Therefore, we basically reverse the process of differentiation. This reverse process is known as anti-differentiation, or finding the primitive function, or finding an indefinite integral.

• The second type of problems involve adding up a very large number of very small quantities and then taking a limit as the size of the quantities approaches zero, while the number of terms tend to infinity.

  This process leads to the definition of the definite integral.

Definite integrals are used for finding area, volume, center of gravity, moment of inertia, work done by a force, and in numerous other applications.

Finding Indefinite Integral Using MATLAB

By definition, if the derivative of a function f(x) is f'(x), then we say that an indefinite integral of f'(x) with respect to x is f(x).

For example, since the derivative (with respect to x) of x² is 2x, we can say that an indefinite integral of 2x is
