I was working on some of my own equations and today i ended up with this differentiation thinghy, I never expected this in my equation but it just turned up :( so if there's anybody out there who loves to solve math please give this a try :)(adsbygoogle = window.adsbygoogle || []).push({});

maybe its too simple :) ... i am just having doubts about the order of the operations and their influences...

me too will try solving it in the mean time...

[tex]\frac{d}{d\theta}\left\{ \nabla\left(\underset{k}{\sum}\left[n_{k}+\theta n_{j}^{\star}\right]z_{k}^{2}\right)^{\frac{1}{2}}\right\} =?[/tex]

[tex]\[

n_{k},n_{j}^{\star}\] [/tex] are independent of [tex]\theta[/tex]

[tex]\[

n_{k},n_{j}^{\star}\] [/tex] depend on x,y,z (grad) (Actually these variables are concentrations defined at each point in our domain)

[tex]\[

z_{k}^{2}\][/tex] is a constant (actually the valence of the kth chemical species)

[tex]\theta[/tex] is also independent of the geometry (x,y,z)... i call it the ALIEN variable :) because afterwards i have to kill it by setting it to zero, that is after differentiation...

Thanks a lot,

Tim
