my equation is
(1/T)=a+b(ln R)+c((ln R)*(ln R)*(ln R))
it is of the form T=f(R);
here T and R are variable. a, b , c are known values
i want above equation to be changed to R=f(T) form?? please give the detail procedure..

In school, we learnt how to solve cubic equations of the form ax3 + bx2 + cx + d.
To factorise it into (x+r)(x+s)(x+t), we have to find a value for r by trial and error (with the factor theorem), then solve a quadratic equation to get the other two roots, s and t.
In the exams, the value of r will usually be 3 or less, so finding r by trial and error will not take a long time.
However, if r is large, finding r by trial and error will take a long time. Are there any faster, more systematic ways of finding r, besides trial and error? —Preceding unsigned comment added by 218.186.9.3 ( talk • contribs) 09:18, 2007 February 13
I any of you [lovely] people have too much spare time on your hands could you give me a hand. I have the formula to work out reps until exhaustion(y) from % of max load (x), and either would like the formula rearanging, or the location of the formula the other way around, its a really nasty formula!:

I can't make heads or tails out of your question. What are reps . Until what exhaustion? 202.168.50.40 22:00, 13 February 2007 (UTC)

Emacs to reformat the result in a WP-friendly manner: round the numbers, pretty-print the
scientific notation, etc. --
Tardis 16:32, 20 February 2007 (UTC)I am currently studying maths at GCSE level (first year) and am finding it relatively easy and relatively boring ("Yes miss, we know how to get a term-to-term rule. Yes, you don't need to give us 15 exercises on it, we get it already. You're not listening are you miss? You're going to give us those 15 exercises anyway aren't you miss, even the the answers are obvious. Oh look miss, you've put the answers on the board and got three wrong. Oh look, you've tried to correct it and got stuck and now you're asking us what the answer is. Well done. Oh look, now you're giving us some exercises that we don't know how to do and which neither the book nor you explain to us. It just gives us the answers without explaining why they are correct. Thanks for that."). As such, I would appreciate it if anyone can give me an equation to solve the includes a bit of everything up to the level of calculus. I've been trying to get my algebra really good, but the textbook I have doesn't really help and only gives basic questions. I am sort of looking for a question with stuff life binomial expansion, negative powers, fractional powers, rearranging divisions and multiplications, the whole lot. I most probably won't be able to solve it, but it will give me a starting point to ask questions about how to do certain sections of it. Thanks for any help you can give. P.S. I apologise for the off topic rant in between the brackets there. -- 80.229.152.246 22:55, 13 February 2007 (UTC)

Thanks very much for those ideas. I'll see if I can do some of them. -- 80.229.152.246 18:07, 16 February 2007 (UTC)
Now this does not make sense. For example: If I borrow $1000 off you and promised to pay you back infinite dollars, it would sounds like an absolute great deal.
and so forth. But this does not make sense at all.
I think we can solve America's national debt. 202.168.50.40 23:39, 13 February 2007 (UTC)
