Are you asking us to evaluate...

?

And also evaluate...

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
