No idea. English math is a bit different than Portuguese math. The name of the stuff, to be more exact.

This is stuff you never touch unless you go past the minimum requirements for math (why you ever would, I don't know) - so for a normal human being that isn't in college or further classes in high school, this isn't supposed to be 'easy' and it's not even something you'd be expected to know how to do.

Unless I literally just didn't notice ever learning this because I pretty much cheesed math, but it looks like calc which isn't a requirement for anything as far as I recall.

Okay good because I never did lol.

Maybe my memory doesn't suck as bad as I think it does.

I think the solution is correct unless i am forgetting something. To confirm it, you can differentiate the answer and you will get back the "original" equation.

Going by wolfram alpha, there's nothing wrong with it.

WebAssign? Yeah, you're fucked. Pm the professor. Hated that shit so much for my stats/math that I just never did the homework.

A mostly gibberish/easy calculus problem that the professor seems to have coded the wrong answer for.

Maybe you're not supposed to capitalize the C.

I took calc 3 semesters ago go fulfill a requirement, and haven't taken one look back since.

But your answer should be correct.. maybe try writing it like {[(mx+b)^8]/8m}+C instead of bringing the 1/8m out front? WebAssign is a pain in the ass.

Can you try it just as a confirmation.

As far as i know, maths do care about whether your c (or any constants alphabets that you chose) was capitalised or not.

these are what the last 8 problems looked like. that's why i was pretty sure it wasn't lowercase.

The question did say "use c for the constant of integration". Though it's strange all the other questions said "use C for the constant of integration". Maybe they want to make the point that following directions is an important skill.

I bet you feel a bit silly now. Even if you are sure it isn't the problem, trying it out is usually helpful.

Man, I hate calculus. I thought integrals were bad, but that's easy as crap compared to Related Rates problems. Shouldn't have taken calculus considering I don't plan on going to college next year.

I honestly can't even solve that and we've gone over it in class. Thankfully most people in my class are having troubles with it as well. Not looking forward to the AP test in May.
Integrals are actually pretty easy after you get the hang of it and memorize all the patterns.

Most computational problems involving integrals are methodical, but every once in a while a problem requires great ingenuity. This is a nice technique, often not taught in standard calculus courses: http://en.wikipedia.org/wiki/Differentiation_under_the_integral_sign
