How can I input integral 1 to 5 on Latex>>>>>>
[tex]\int_1^5 {x{e^{{x^2}}}dx} [/tex] gives $\displaystyle \int_1^5 {x{e^{{x^2}}}dx} $.
This subforum will help you with the code. Once you begin, you quickly learn the code.
[TEX](5+2\sqrt{6})^{x^2-3}+(5-2\sqrt{6})^{x^2-3} [/TEX] gives $\displaystyle (5+2\sqrt{6})^{x^2-3}+(5-2\sqrt{6})^{x^2-3} $
If you click on the “go advanced tab” you should see $\displaystyle \boxed{\Sigma} $ on the tool-bar. That gives the [TEX]..[/TEX] wrap. Your LaTeX code goes between them.
