Calculus help

[boostedfury]

Ok guys idk what to say other than is anyone good at Calculus.. This class is killing me so far and it's finals week. Right now I am stuck and would love some answers if possible for this take home test I have. I need to do good to try and salvage this damn summer class I am taking! anyone reply and I can keep you busy hahah

[J.Ralli]

lemme know what you need, i remember a lil

[omgjacki]

Post it in here. I've never taken calculus but I want to see what I can do =P

[boostedfury]

ok guys here it goes find teh derivative of teh function ..... f (x)= e^x + x^3 -xe^x

[boostedfury]

i have no clue where to begin

[The Captain]

mmm'mmm derivatives. If this was 2 years ago, i'd have no problem doing that in my head. I've taken 3 advanced calculus classes. Problem is, i've forgotten it all.

[omgjacki]

WOAH!

Does PEMDAS apply in this matter?

[J.Ralli]

no pemdas lmao

[boostedfury]

haha tell me about it..i got like 6 more problems that I need done for this damn takehome test that I started at 7pm...and the best part a Cumulative final on thursday haah my head right now is throbbing and I am stressing out like a mother****er

e^x + 3x^2 - xe^x - e^x = 3x^2 - xe^x

The derivative (af+bg)' for real numbers a,b and functions f,g = af' + bg'. In other words, you find the derivative of each part added or subtracted together separately.

The derivative of e^x is e^x.

The derivative of ax^b = abx^(b-1), in this case a = 1 and b = 3, which is 3x^2.

The derivative (fg)' which is the product of two functions f and g = fg' + f'g. In other words, you take the derivative of the first function times the second function plus the derivative of the second function times the first function. In this case, f = x and g = e^x, so you get xe^x + e^x, and when you distribute the - you get the above result.

hahah dear god whitefire u wanna answer some more?

[boostedfury]

ok heres another one if anyone wants to tackle this: Evaluate the following integral:
Integral ((x^4 - X^ (6/5)) dx

[J.Ralli]

i give up lol

[boostedfury]

nah u know how I feel Jome.. I am a business major hahah

(1/5)x^5 - (5/11)x^(11/5) + c

The indefinite integral of x^n = (1/(n+1))x^(n+1) + c, where c is an arbitrary constant.

If we still had rep points, i'd give Whitefire on for being FTW

[CleanNeon98]

TST, its everything you need lol

[omgjacki]

We had rep points for like a minute. If we still had them Cleanneon would be banned already =P JK
But I would give WhiteXFire lots of points, too.

[boostedfury]

omg Whitefire you are awesome.. want any more lol?
