Thanks for letting me know. Don't know why it is doing that, it's just a regular pdf file.
Anyway, here is the problem:
r=(sec theta + tan theta)^-6
The answer I got is:
-6(sec theta + tan theta)^-7(sec theta tan theta + sec^2 theta)
If anyone could confirm that this answer is correct, that would be helpful.
Thanks again
Brad
It looks good to me. You might want to visit our LaTeX Help Forum. It looks difficult, but once you get the basics it's actually rather easy.
