Only class I ever failed in high school was Algebra 2. Not only did I go on to ace it in summer school, but the next school year I took pre-cal/trig and got B grades.

Conspiracy much?

Help needed.

How does

(DZ)e^-Z = (DT)T

go to

-e^-z = t^2/2 + c

I get the right part, but not the left, with the exponent a variable.

Ok, take your first expression and divide through by DT, so you have

(DZ/DT)e^-z = T

Then integrate w.r.t. T.

There's probably more steps to get the DT over to the other side (it's been a couple years since I did math) but that is the basic concept...

Haha, it is hard to explain Maths online. I have a degree in it so I couldn't help myself, but even just looking at that made me realise I am rusty as **** at it.

What's funnier though is that i made this thread completely in jest, and now it's actually helping people with math.

I enjoy Algebra and Geometry. Not algebra 2, just 1

My bachelors was Applied Mathematics, so if you're asking for help with calc II or III I might be able to help you out. The biggest challenge is, as UKfan mentioned a few posts above, trying to explain/show the steps of solving a given problem without being able to really use the proper symbols on a forum.

My degrees says Mathematics but it means Espionage. (2 years of algebra and a year of analysis... and a bit of other stuff)

I also studied computer science. So I might be useful if you have a question or two.

y-yes... of course it equals five.

Not really a huge fan of math. Chemistry and Biology are more of my things.

took calc last semester, was terrified of it in high school, so i waited til college. definitely not as hard as its made out to be. pretty easy actually. that being said, i ******* hate math.

I am in Calc 2, what that has to do with Accounting I will never know.

(16/9)^-3/2

I know the answer, but idk how to show the work...help?

Not sure on the formal way to do it so these could be out of order but if you take the 16/9 and flip it to 9/16 then you have (9/16)^3/2 to get rid of the negative. Take the square root for the 1/2 and it's (3/4)^3, which is 27/64 and should be the answer you got unless I'm misinterpreting your expression.

studying for a test someone must be here all day to help me!

1st question

Evaluate each function at the given values of the independent variable and simplify.

1.) f(x) = 4x + 5

a.) f(6)
b.) f(x + 1)
c.) f(-x)

EDIT: I think I remember it now, correct if I'm wrong but I would just plug in 6 for X in the equation for A. and same goes for all the other ones right?

yes... that's exactly right.

a) f(6)=4*6+5=29
b) f(x+1)=4*(x+1)+5=4x+9
c) f(-x)=4*-x+5=-4x+5

I remember when that was a difficult concept for me... it is so incredibly easy though.
