hi

i have a equation which i dont know how to solve it, as i have never seen this equation before !!

question

given : V=B-q/k In(r-1)

make r subject of the formula ?

could you please explain what they want exactly

They want you to solve for r in terms of the other pronumerals. I suggest that you first attempt to make ln(r-1) the subject.

By the way, your expression is ambiguous. Is it meant to be V=B-q/[k In(r-1)] or V=[B-q/k] In(r-1) ....?? Or V=(B-q)/[k In(r-1)] or V=B-(q/[k In(r-1)]) etc. etc. Please use bracketes, or take the couple of minutes to learn how to use latex (click on the appropriate link in my signature). - Oct 6th 2010, 01:34 PMmanfred

I hope you do NOT mean that the only equations you can solve are those that you have seen before!
