<p>Hello,<br>
<br>
My name is Erika Bello and I'm a college student trying to figure out how to use LaTeX. I have looked everywhere online and on videos and copied the codes but I cannot reproduce a double or triple integral. I know the codes are \iint and \iiint but they do
not work. Not even when I type $\iint$ or $$\iint$$. I have asked my calculus professor as well but he only tells me to type \iiint.<br>
<br>
Is there any manual for codes like these? I have attached a document with symbols that I need to use but so far I am very clueless about all of the parts surrounding integrals. I want to know how to type multiple integrals and their limits. <br>
<br>
Thank you very much for your time!<br>
<br>
<br>
Erika Bello<br>
