If a=b then integral(a) = integral(b) .... 1/2lnx =/= 1/2ln(2x)
2016年2月14日 · Yea that's right. I just evaluated the definite integral from 1 to 2 and they were equal then. I suppose my real confusion is coming from some where else in my (parent) equation (not this one) I'll have to get back to you in a bit.
How to Integrate ∫(e^2lnx)(10x)dx? - Physics Forums
2013年10月27日 · Hi everyone, I just started to study Physics and I have a very simple question about integration. I'm blocked on this for a while. I'm trying to solve a differential equation for which I need to integrate the expression: ∫(e^2lnx)(10x)dx Does …
Test the set of functions for linear independence in F - Physics …
2012年2月19日 · 2ln2 - 2ln2 - 2lnx + 2lnx = 0 Which is always true, therefore the functions ARE linearly independent. My understanding of some of these concepts is probably shaky, since reading through this I still haven't managed to convince myself that this is true (like for instance, how did the values for b and c come about? guess and check?).
Find equation tangent to y=(x^2)lnx at (1,0) - Physics Forums
2014年1月26日 · Homework Statement Find an equation for the line y=(x^2)lnx at (1,0) Homework Equations The Attempt at a Solution I took the first derivative of the equation and got y'=2xlnx +x In other equations, it would be simple to find the slope, but at this point I am lost, is the slope 2...
Increasing/Decreasing Intervals and Limits - Physics Forums
2013年6月13日 · 2lnx = -2 lnx= -1 So I think x is somewhere between 0.10 and 1.00? (ln x)^2 + x(2ln x)(1/x) is the first ...

2005年1月20日 · it is lnx^2 (the first one) and i can't graph it. i don't know how. I've found all of the info ex. domain, asymptotes,intervals of increase/decrease, local min/max, concavity, and Inflection points
L'Hopital on limit of tanx(lnx) as x ->0 (from the right). - Physics …
2012年3月21日 · [itex]\frac{2lnx(\frac{1}{x})}{\frac{cosx(cosx+2xsinx}{x^2}}[/itex] And then applying the limit as x -->0 gives ∞/∞ again. But applying L'Hopital again just seems like it will get really complicated as you say.-----So I have a few questions.
