I think I'm following you've if 4-root(y) means y1/4. Regardless that doesn't look right? Thanks for the interest though :). We should be able to get a concrete answer like 16ln2 or something if i remember correctly!

no its (ln2)^4 not ln2^4=4ln2 solving this I believe involves setting it equal to σ or some variable and then exponentiating using e. Although I could be completely wrong. I know this can be simplified and solve because my professor did it in class, I just can't find my notes from that day.

Homework Statement Im trying to simply (lnx)^n say (ln2)^3 Homework Equations ? The Attempt at a Solution Im lost on this one I can't find any information. All info I'm finding is dilute because of similar search terms. Please, and thanks!

oooo great, will do

Its not coming out the same, I don't get it?

Well yes or coarse you silly goose. I guess i need to plug in some numbers and see if they work out. Ill report back shortly.

Yeah I can see it but my answer didn't match up with what Wolfram gave. they gave 1/13 e^(3 x) (3 cos(2 x)+2 sin(2 x)) And what am I missing why do your equations look so much...prettier?

y=∫e3xcos(2x)dx where u=e3x du=3e3x & v=(1/2)sin(2x) dv=cos(2x) After integrating by parts twice i get this y=e3xsin(2x)/2 - e3xsin(2x)/2 +sin2xe3x/2 -∫e3xcos(2x)dx the 2nd time I integrated by parts it was u=sin2x du=2cos(2x) v=(1/3)e3x dv=e3x

Homework Statement Integrate By Parts (i.e. not using formulas) ∫e3xcos(2x)dx The Attempt at a Solution I keep going around in circles, I know at some point I should be able to subtract the original integral across the = and then divide out the coefficient and that's the final...

Ive never heard of this, but "ground up" is exactly what I want! Anybody know a "ground up" book in relation to physics.

Yeah its pretty hard to describe but I want resources for building from the "ground up" a complete and concise understanding of the fundamental principles of math/number theory/algebra/calculus, which we all know is the foundation on which physics rests. Maybe its just that almost at the end of...

Well...were should it go?

Ok so this is kinda wishy washy but I don't know how else to explain this other than I feel like I am missing a critical piece of information as far as fundamental "math" goes. I am highly intelligent and and am a Mechanical Engineering Major who gets all A's, but I feel like I am missing a...
