evaluate the integral

Are you asking us to evaluate...
$\displaystyle \int_0^4 x^2 - 6x dx$?
And also evaluate...
$\displaystyle \sum_{n=1}^{\infty} \frac{1}{n}$
This is the code for integrals.
[tex]\int_{lower limit}^{upper limit} {function} dx[/m ath]
Copy it, replace appropriate parts, delete the space between the m and a in [/m ath]
Similarly here is the code for sums
[tex]\sum_{n=lower limit}^{upper limit} {function}[/M ATH]
for fractions...
\frac{upper}{lower}
For infinity its \infty
