The Mathematics Club ~ *ΜΑΘ* ~

Well, I sure forgot about this place @-@ Nyeh... I remembered it because I have somewhat mehish news.

I only have two more math classes left until I've finished all of the math I need in college :/ Calculus II and Stats. Everything after would be an empty credit. So I'm quite sad, yet happy.
 
Username: i dont know
Overall Education Level: 12th grade
Mathematics Education Level (Or most recent/advanced math subject): im pretty much thorough on all forms of algebra, euclidean and cartesian geometry and basic multivariable calculus.
Do you think you can be asked for help in your level or lower?: sure. as long as you dont ask me questions about statistics. i hate statistics.
 
Username: Corvidae
Overall Education Level: Going into Freshman year college next year
Mathematics Level (Or most recent/advanced math subject): I took stats and calculus, but I was horrible at stats and my calculus is rusty.
Do you think you can be asked for help in your level or lower?: Pre-calc and I'm there. I'm taking calculus in college again for a reason.
 
This thread needs a deserved bump :)

I remember posting here before, don't know why I stopped...

Anyways, I've got my advance math classes these days, and they are just so unappealing.
Stupid Differential Calculus or whatever it's called.

I'm stuck on these questions, I'm afraid to admit, I need to work over them again x)

Ooo! I took that last semester at the community college I attend :3 I might be able to help :D I made an A in the class and I'm currently in Integral Calculus myself.
 
Ahh. Calculus. XD I took that last... spring. I might have to take it again in the winter quarter. I need some practice, I'm already rusty. =\
 
I'm studying calculus right now. I might be able to help as well.

In fact, I have an exam based on Differentiation and Integration in a few days.
 
Could you guys give this question a try:

[PokeCommunity.com] The Mathematics Club ~ *ΜΑΘ* ~


I was able to integrate it using the substitution t^20 = x and got a long answer. Is there an easier way to solve it?
 
I've been doing some more thinking on your problem and have come up with a possible simplification.

You could try the substitution t = x^k^-1, where k is any real number.

What that does is inverse the power so you still end up with t^5 and t^4 on the denominator but it should simplify the numerator and make the integrand easier to tackle. I haven't run through the maths or anything but if you want, try it and see.
 
You mean take t = x^(1/20)? (t = x^20^-1 ?)

I tried that, gives a long answer. It requires applying the binomial theorem with a power of 15)

Or something else like t = 1/x^k? How? :/
 
I meant what I typed out exactly.

t = x^k^-1

So for the first term you have x^(1/5) so the transformation gives t^5 and the second term goes from x^(1/4) to t^4

If that makes sense.

Edit: The transformation inverses the power of x or in other words you flip the fractions over.
