hi,

what is the derivative of:
d/dx arcsec(4x+3)?
I also want to know the integral of
1 / (x^2+4x-9)^(1/2) dx

Thank you,

Man, if you'd spent the time that you keep coming back into #tremulous and asking math questions actually *learning* how to do derivatives, you'd probably know the answers to these already.

Is the OP using the carat because he doesn't realize Simple Machines offers superscript¹ and text sizing?

¹Example given.

@OP: I recommend finding the area under the curve represented by the average sarcasm of the above posts.

This forum (well, entire website) is about a video game called "Tremulous".

I think that a website about math would be of more use to you. Try here: http://mathworld.wolfram.com/

Let S equal the total amount of sarcasm, where a is the initial post, and b represents the locking post, graphed as a function of x, namely f(x), where x represents the time wasted seeking such answers here, and y represents the OP's average frustration quotient, or FQ. Note that frustration vs. time wasted produces a sinusoidal wave of expectancy that the question may be answered correctly, which forms the upper limit of the area of sarcasm.

Why don't you go ask in #math?

Rocinante · « **Reply #10 on:** March 25, 2008, 04:14:26 pm »

He's banned in #math. Or so he keeps saying.

Taiyo.uk · « **Reply #11 on:** March 25, 2008, 04:15:09 pm »

Banned for asking too many Tremulous related questions?

I laughed so hard.

Aw, I wanted to get him to say it.

It's just not the same this way.

Hmm, TheLichKing, want to make a deal? I'm going to ask all your math questions and you're going to ask all my trem questions?

not like he's going ot read it

He just joined the forum to ask this and never logged in ever since as far as I see in his profile

theLichKing makes me sad.

The derivative of arcsecant is fairly straightforward. It's the sort of thing that even tends to be listed in the front cover of the textbook.

Or hell, you can even type "integration" into Google.

theLichKing · « **Reply #17 on:** April 06, 2008, 09:27:03 am »

why are you guys giving me definite answers?? this is an indefinite integral.. it is the antiderivative, not the area under the curve. help again plz, thank you, come again

and don't tell me to go to #math.. i am banned

i asked them how to divide by zero. they showed me this and i don't understand what it means $:-\$ $:-\$

You sound like a hacker/spammer we had on a server just now...

@theLichKing: Since you are banned from the Tremulous IRC channel for the exact same actions as you exercise here, I lock this topic and hope you will refrain from boring us with your math questions. If you do not, your IRC ban will be extended to the forums.
