Question

What is the limit of s as it approaches 7?
lim [(1/s)-(1/7)]/s-7

Answer 1

\[\Large \lim_{s\rightarrow7}\left[\frac1s - \frac17\right](s-7)\]

Answer 2

Did you try simplifying?

Answer 3

Or actually, never mind... why don't you just downright replace s with 7? It doesn't result in anything ugly or undefined or anything.

Answer 4

its 1/s - 1/7 OVER s-7

Answer 5

Oh... sorry :)
I just had that feeling that it was too easy.. but anyway
\[\huge\lim_{s\rightarrow 7}\frac{\frac1s - \frac17}{s-7}\]

Answer 6

yup!

Answer 7

Well, I suggest you simplify
\[\Large \frac1s - \frac17\] into just one fraction.

Answer 8

but wouldn't equal to 0?

Answer 9

It won't. Anyway, simplify?

Answer 10

okey how do you do that?

Answer 11

Seriously? -_-
That's elementary stuff.... and you're in calculus XD

But... not here to judge (not so harshly anyway :P )

\[\Large \frac{a}b-\frac{c}d = \frac{ad - bc}{bd}\]

Answer 12

Stay with me here @jbeloy17

Answer 13

sorry about that.

Answer 14

i think i got it.. is the answer 51/2500?
