∫(7/(1+x^2))

We just started integration and I've got a take home test due tomorrow, and can't get this simple part //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

$4 paypal to the first person to solve it!

7 * inverse tangent of x +c

the other answers are incorrect because the integral has no limits of integration, requiring a + c.

GJ dumple you beat me!

 

[maldecido33 10+ year member]

It was so easy you don't need paper....

pm'ed you with my PP.

Also, if you don't include the +c you will get it wrong.

eh some times it helps but anyway i like math but am studying for history edu

 

[maldecido33 10+ year member]

rub it in

my entire integral was

∫(7/(1+x^2)) +sin(x) -5e^x)

to which I got

7*inv tan(x) - cos(x) - 5e^x + c

look right?

 

[pwnt by pat 10+ year member]

yep.

You're just taking calc1? That's calc2 material

lol cool. Thanks man

 

[maldecido33 10+ year member]

yea, cal1

end of the semester, i suppose.

Last thing we covered was finding the area of the limit of a sum

no fun //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

but I've got 15 more hours of math left

i'm excited
