Try this .....

insert \frac{a+b}{c}

between the "\(" delimiters - you need the "/" in front of the second "tex" inside the terminating square brackets.

And you then get what you wanted ...

\(\frac{a+b}{c}\)\)

\(\frac{a + b}{c}\)



Hope it helps. Note the slash is backwards.

Something I've found odd doing this for the book, the finished product is actually an illustration. You can copy and paste it as such.

And I thank you, too, Bill. Little things were throwing me off. Now I think I'm ready to learn this thing. Is it okay if I practice on this board or is there another place reserved for practice?

This should be V1 with 1 subscripted:

\(V_1\)

Excellent. Now what about Vout?

\(V_out\)

Nope, trying again...

\(V_{out}\)

That woiked!

Now howabout a superscript such as 2^2 = 4?

\(2^2 = 4\)

Excellent. What about 2^10 = 1024?

\(2^10 = 1024\)

Nope, we need brackets...

\(2^{10} = 1024\)

Ok, the point about more than two digits in an operand needing brackets is well taken. Here's tp printing sqrt{144} = 12 and getting it right the first time!

\(sqrt{144} = 12\)

Yahoo! I'm on my way! Now for something a little more complicated. But we'll do that tomorrow. ;)

Awesome, Bill! Thanks! As soon as I get some ink for my printer I'll copy these lists and keep them next to my computer. Gotta mow a few lawns first. ;)

Okay, I just ran into a problem. I tried to write the formula for an RC filter, which is 1/(2*pi*R*C) in the form you would find it in a book and I did this (without the TEX parameters:

\frac{1}{2piRC}\

which gives this:

\(\frac{1}{2piRC}\\)

But I would rather have a nice looking pi. So.... I read up on it and it seems \pi will do the trick....

Without tex I wrote: \frac{1}{2\piRC}\ the \pi supposedly creating an actual Greek pi....

\(\frac{1}{2\piRC}\\)

That didn't work. Anyone out there got a suggestion?

Let's try this: \frac{1}{2\{pi}RC}\

\(\frac{1}{2\{pi}RC}\\)

Nope.

You need a space after the /pi and the RC
\( \frac{1}{2\pi RC}\\)

Rich (BB code):
that is  \frac{1}{2\pi RC}\
                      ^ notice the space

Here is the equation for an RC filter.

\(f = \frac{1}{2\pi RC}\\)
Well, that worked. So let's try other symbols:

\(V(t) = cos(\omega t + \phi)\)

I forgot the constant Vmax......

\(V(t) = V_{max}cos(\omega t + \phi)\)

What about sigma used for integration?

\(\sigma \)

That's the small one. Here's the big one from the symbol menu...

This is big Ʃ
