Hi f95toli, Thank you for taking the time to respond to my question. Thats what I was afraid, I'm basically carrying out this experiment in the lab and have all the other values but couldn't get this equation solved for sigma(s). I'm not too sure what to do if there's no way the...

Hi, I've been having some problems trying to re-arrange this equation for a few days now, the problem is that sigma(s) appears twice in the equation: http://screencast.com/t/dlDwH4eIcp The problem seems to be that I always end up with complex roots rather than a single equation for...

Sorry guys, still not had any luck with this. I've also tried wolframAlpha with this: http://www.wolframalpha.com/input/?i=solve+a%3D+%28%28b%5E0.5+%2F+c%5E0.5%29+*+exp%28-d*%28c-b%29%5E2%29%29+for+b ( I just separated the terms in order, into a,b,c,d) But get this error: Standard...

Sorry SteamKing, you are correct. I think I've mixed both the symbols up during my which I'll be sure to fix :) My problem still holds true, would you have any thoughts on that? Thanks =)

Hi, I'm trying to solve this equation inside of Maple: http://screencast.com/t/EeqzLhxS for gamma(s) I assign variables to each of the values like this:http://screencast.com/t/DBLS8BH6R When I try to solve I get this weird answer with a new _z variable...

Wow thanks so much guys that's been driving me crazy! I can't believe I never figured that out! You guys are lifesavers :)

Hi all! I have tried to calculate a1 using Maple as shown here: http://screencast.com/t/iV1XwJ1CXiqU The problem is when I do this exact same calculation by hand with the exact same values I always end up with 59.99 but Maple gets 65.03? How can there be such a big difference? Thanks!

Thanks HallsOfIvy, Does this look correct to you? I mixed the terms up so now C if F and D is Z New equation link:

I wish but I'm afraid they are all compulsory classes.

Hi all, I was looking for some advice for my course as I have just entered the final semester of my final year and already find the workload overwhelming. I'm also trying to avoid leaving everything last minute like I usually do :) This semester I have 5 classes and a thesis to write(as...

Hi, So I have this simple equation that I'm trying to solve in mathematica , the problem is that although I have all the different values and equation I can't seem to get the solve command to solve it - http://screencast.com/t/a8REzNM0cxSS Any thoughts on what I'm doing wrong? Dave,

Hi LastOneStanding, Thanks very much that method does seem more efficient but I think we're supposed to do this is through substitution as that's the method our teacher has been using in class. Although I'm sure it will be a lot messier. So what would be the best way to approach this using...

Hi LastOneStanding, I'm really sorry you are completely right, I wrote the equation wrong it should be: http://screencast.com/t/Y8QobUXVB3S3 Although I still have the problem getting my head around that logic I mentioned before. Thanks!

Homework Statement Hello all, I'm trying to solve for 3 unknowns x,y,z. We are given these formulas: http://screencast.com/t/Y8QobUXVB3S3 Homework Equations Please see link provided above. The Attempt at a Solution I first rearrage for root(x) then I rearrange equation 2 for root(y), I...

Great! Thanks so much TSny :) I have a similar problem regarding rotational energy levels that seems to be confusing me: Can somebody please tell me what's meant here by calculating the spacing?- a(i) - http://screencast.com/t/BK8BsW7r We have these formulas available...
