hey guys I got most of them solved thanks for the help. All i got left is these following

Here are the problems just view the image of the paper.

If you can all just check them to see if there right my biggest concerns are 7,8, and 12

I can do it if it is basic cal. i Have an A in business calculus right now what are you studying?

calculus may be calculus but what he probably means is that business calc sounds like a basic course or something like "calculus 1" as opposed to an advanced calc course.

If you have just a few Q I can help you later on via AIM for free.

You're correct. Calculus is calculus. Unfortunately, business calculus is not. Some might even say its a joke.

Bump I just added the questions I need these answered by tonight please help me with those.

here it is again

Differentiate

Find first and 2nd derivative

(-2)/(x^2 + 2x + 1)

Find absolute max and minimum values of the function, if they exist.

f(x) = -8x^3 +9x^2 + 6x -2

Differentiate

ln 4x

e^3x^2

e^x / ln x

the ti-89 calculator does this iirc. But one of the points of calculus 1 is to memorize the derivative rules. Using a calculator like that totally defeats the purpose. ?

8 is right. At first, I thought it was wrong, but it's right. If you need the work, I figure

ln(4x)' = 1/4x li d/dx 4x <---chain rule

1/4x li 4 <deriv of 4x

=4/4x

=1/x

...right?

ok 7) take the derivative of what is inside the e^()

Dx -> 3X^2 = 6X

and multiply that by f(x) -> 6Xlie^(3x^2)

8) it's the same as 6 if the derivative of ln(x) = dx/x then the derivative of ln(4x) = 4/x.

12) you can't cancel out of the ln(x) from the top because it isn't in the second term.

So, if you need to pay someone to do your homework for you, what are you planning on doing for the exam?

Your money would be better spent on a REAL tutor who can sit down with you and help you actually LEARN the material.

thanks for your concern but it sound more like sarcasm. I did get tutored as she worked the problems out for me. I just needed to see them worked out as I know how to do it at least 60% of it I just need too see it done to learn the parts I dont know. Plus it was interactive session I can ask her questions and everything. I am not advertising for the site as I dont get a dime for you going there I am just saying incase some1 finds themselves in the same predicament as I was in.

I know this makes me sound like a huge dork, but I miss Calculus. I wish I hadn't been forced into basic algebra freshman year at Purdue and had gone straight into calc..I would have done much better.

Seems I forgot basic algebra since I hadn't had it really, since 8th grade. /

I have also forgotten most of my advanced math that I had learned. cry

those are all the correct answers brodie has

a few rules that will make this very easy

derivative of E^x ='s (e^x) li the derivative of wats up top

derivative of ln(x) is (1/x) li the derivative of wats inside the ln

product rule is when 2 terms are multipled example is

(2x)li(E^x)

take derivative of the first term times the 2nd term + the derivative of the 2nd term times the first in this case it would be

(2)(E^x) + (e^x)(2x)

quotient rule= derivative of top times the bottom term - the derivate of the bottom times the top all over the bottom term squared

E^x/lnx= (lnx)(e^x) - (e^x)(l/x))/(lnx)^2

power rules ='s multiply the term by the power and drop it by one

5x^5 ='s 5li5x^4 which is 25x^4
