How-To: Enter an integral expression - OpenOffice.org Math
- To enter an integral expression, first click on the "math commands window" here.
- Now, once the cursor appears, type in the word "int." This should display the integral symbol.
- Afterwards, press space and type in the function or expression that you want to use for the integral expression. In this case we entered "g(x)."
- Good! We have entered a integral expression.
- Now, you can also add upper and lower limits to your integral. To do this, first move your cursor in between the word "int" and the function.
- Make sure to have at least one space from the word "int." Now, to enter the lower limit first, type in the word "from."
- Next, press space and then type in the lower limit that you want. In this case it is "n=3."
- Afterwards, press space. Now, to enter the upper limit, type in the word "to."
- Then, press space and type in the upper limit that you want to use. In this case we want to use the infinity symbol. We simply type in "infinity" to do this.
- Finally, make sure that there is a space between the upper limit and the function by pressing space.
- Great! You have learned how to enter an integral with upper and lower limits. Congratulations!
