latex delimiters

Is there a way of embedding LaTex into posts w/o using the LaTex button and dialogue?

Other boards have $$, [tex][/tex], [math][/math]

You know what guarantees I won't look at your problem?

Using the words ASAP, or fast, or now, or anything similar in your title.

You're all quite fortunate to have the group of us here that answer your questions.

sub forums

It might be nice to have a few sub forums so we know better how to address given problems.

For example I suspect we sometimes use calculus to answer questions posted by people in pre-calculus classes.

Why do sometimes we get the option to filter out answered questions but sometimes we don't?

I'm concerned that we are just doing people's homework for them. That's no way to encourage people to actually learn the math.

34 1/2 inches minus 33 7/8 inches

There's a couple ways you can do this.

1) you can convert the whole thing to 1/8's of an inch.

34 1/2 inches = 8x34 + 8x(1/2) = 276 (1/8 inches)

33 7/8 inches = 8x33 + 7 = 271 (1/8 inches)

so 34 1/2 - 33 7/8 inches = 276 - 271 (1/8 inches) = 5 (1/8 inches) = 5/8 inch

2) you can notice that 7/8 > 1/2 so you need to borrow a 1 from the 34.

then you have 34 1/2 inches - 33 7/8 inches = 33 + 1 1/2 inches - 33 7/8 inches = 1 1/2 - 7/8 inches

now you convert the 1 1/2 to 1/8ths to get

1 1/2 - 7/8 inches = 12/8 - 7/8 inches = 5/8 inches

15x^2+x-14

with a little trial and error you can find that 15x^2+x-14 = (15x - 14)(x + 1)

if you mean what is the answer of 15x^2+x-14=0 you can see from the factors it's x = 14/15 and x = -1

your grade is the percent of the questions you got right on the test.

so you would take (# questions you got right)/(total # questions) * 100%

I'll let you punch the buttons.

I did.

But note that a cycle isn't really a unit. Hz is 1/s, not cycles/s.

(1/s) / (m/s) = 1/s * s/m = 1/m

my bad.
