yeah so this is pretty low, i know, im a loser (if you're good at calc help me)

[insertnamehere]

ummm yeah so i have this homework thats due in slightly less than three hours, i dont understand it at all, no one i asked knows or will help me, and pretty much im crying becasue i dont want to fail calculus 1 for the second time around and im headed in that direction.....

anyone handy with antiderivatives? Find the most general antiderivative of this function

f(x) = 2e^x + 9 sec^2(x)

if you can do that and explain how it works, i can do a couple more of the problems. exciting, eh?


i hate my life

i use to know this shit but i took calc a few years ago

Hey Bob, I think I see potential for your first customer. Why don't you give her your digits.

[zorra_chiflada]

hit me with the digits

[Bob]

the business is phone calculators, not phone calculus. easy adding and subtracting only. multiplication and division for a little extra. square roots for special customers. nothing more complex than that.

i took calculus in my sophomore year of college....for one day. i dropped it immediately and i don't regret it.

[ericlee]

I've never seen that shit before. Can someone explain to me how it can be beneficial to everyday life please?

[insertnamehere]

cause then i can answer stuff like this!
Since raindrops grow as they fall, their surface area increases and therefore the resistance to their falling increases. A raindrop has an initial downward velocity of 10 m/s and its downward acceleration is given by the function below.

a={(9-0.9t ( if ) 0<=t<=10,
0 ( if ) t > 10)

If the raindrop is initially 500 m above the ground, how long does it take to fall?

[insertnamehere]

nobody cares but it was (9*e^x) + (9*tan(x))

8 down, 12 to go.... most of which are scary word problems that i dont understand....

[ericlee]

I don't think it's the fact that nobody cares. It's just that nobody's here. It's how it is on the weekends here, hence my Sunday thread. I'm sooooo lucky to work on the weekends.:(

[jabumbo]

just know that e^x doesn't change when integrated


and all those trig functions you use the chart that tells you what each one changes too...



chain method rules!

[Documad]

I used to be really good at it, and now it doesn't even look familiar.

I'm shaking my head gently back and forth, btw.

[insertnamehere]

hey jabumbo, i was looking for you online earlier haha. engineering students of the world unite! actually, im not an engineering student, but maybe one day... if i dont fail out of school

anyway, time's all up. i got like a 15/20 on my first set and actually managed a 9.5/9.5 on the second.

this was a colaborative effort between me and two other people

[cosmo105]

i was pretty decent at calculus when i took it both in high school (JAIME ESCALANTE PROGRAM WHAT! GANAS!) and again in college (I FORGOT EVERYTHING WHAT!) and now i don't remember shit (y)
