I do not understand what you mean by ‘represent the integral’, so I will take some guesses:
- To do a numerical integration with a function, use the integral function.
- To do a numerical integration with data, use the trapz function.
- To do a symbolic integration, use the int function.
- To display an integral as you might see it in a textbook or paper, see the documentation on Text Properties, specifically with respect to using the LaTeX interpreter.
