I have moved this thread into the forum which has all the help you need. Tip: use [tex][/tex] tags for now, instead of the math tags.
You're given the parametric equation of a curve:
Find the slope of the graph when t > 0.
Can anyone direct me to the thread that teaches you how to use LATEX??
Apart from replacing the [tex] [/tex] tags by [TEX] [/TEX], you need to be careful about a couple of other things:
1. Don't write \pit (TeX will think that "pit" is a command). Instead, you should leave a space after \pi. In fact, that is good practice with all TeX commands.
2. Use braces { }, not parentheses ( ), in expressions like t^{b-1}. Tex will only treat the first character after ^ as a superscript unless you use braces. If you write t^(b-1), it will come out as
,
with just the opening parenthesis superscripted.
Finally, the dialect of TeX used in this forum is a bit touchy about carriage returns (basically, it doesn't like them). So write your equations as
[TEX] x = y [/TEX] (all on one line)
rather than
[TEX]
x=y
[/TEX],
and enclose each line of TeX in separate [TEX] [/TEX] tags.
Put those little things right, and your TeX will come out nicely, as above.
