[mortal rose]

Ignore writing on the top

[vast fiber]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Well if t approaches 0+ that means |t|=t

Seems undefined to me

[deft patrol]

...how so?

Wait, duh.

Wait, no.

[amber pasture]

yeah this is the limit of a constant

[fresh zephyr]

Wouldn’t the t then cancel eachother out

Oh wait I see it

[flint coral]

Well yes it would cancel out that’s why I think it’s undefined

[fresh zephyr]

Yea limit of undefined consant

[autumn shoal]

the answer is undefined

$|t|/t$ is the signum function

[surreal stone]

No Lifer (aka No Lifer)

[autumn shoal]

the limit of that as u approach from the right side is 1

so

$\sec{(\frac{\pi}{2})}$

[surreal stone]

No Lifer (aka No Lifer)

[autumn shoal]

which is undefined

or you can say $\infty$ if required

[surreal stone]

No Lifer (aka No Lifer)

[fresh zephyr]

Why would sec(pi/2) be positive infinity?

[autumn shoal]

well

alr

undefined

1/0, whatever
