I think I get it now... when I'm home from work I'll sit down, work through it and post the answer. Thanks again, your help is very appreciated guys.

Sorry... I don't know how to figure that out.

Homework Statement Prove each statement using the epsilon delta definition of limit. lim (x^2-1)=3 x -> -2 Homework Equations The Attempt at a Solution Given E > 0, we need D > 0 such that if |x-(-2)|<D then |(x^2-4|<E. If |x+2|<1, then -1<x+2<1 -5<x-2<-3...

Hi, thanks for taking the time to help. It's really appreciated. I have a vague understanding that this question isn't asking for a single answer. Your explanation is helpful. Isn't it comp, and not proj? (This is what my book gives, at least.) I didn't use it because I don't really understand...

Homework Statement If a=<3,-1> , find vector b such that comp_ab=2 Homework Equations comp_ab=\frac{a.b}{|a|} The Attempt at a Solution Still not entirely surecomp_ab is, exactly... is it C in the below? Lost...

Oh, so I'm right? How anti-climatic... Thanks again.

Hi, thanks for the reply. No, the original equation is as appears.

Homework Statement Write the quantity using sums and differences of simpler logarithmic expressions. Express the answer so that logarithms of products, quotients, and powers do not appear. log_{10}\frac{3}{\sqrt{1+x}} Homework Equations The Attempt at a Solution The...

Thanks!

Thanks for the direction! I think I've got it... It's late and I still suck at LaTeX, is it okay to do this, or is it against etiquette? Thanks again for your help!

Homework Statement 2^{5x}=3^x(5^{x+3}) Homework Equations The Attempt at a Solution ln2^{5x}=ln3^x(ln5^{x+3}) 5xln2=xln3(x+3)ln5 Here's where I get stuck... I've tried a bunch of different manipulation, but can't seem to isolate x... Thanks in advance!
