Algebra problem............?

If
(F/B)^(?*cot?) = (2?*P*cot? + 2Y)

prove that

p=Y(1+(tan?)/?)(1-(F/B)^(?*cot?))

Re: Algebra problem............?

Is it to prove

$(\frac{F}{B})^{\mu\cot\alpha}= 2\mu P \cot\alpha + 2Y \to P=Y(1+\frac{\tan\alpha}{\mu})(1-(\frac{F}{B})^{\mu\cot\alpha})$ ?

Stainburg .. YES

Re: Algebra problem............?

I guess it can't be proven ... but is there even an approximation ?

Me too. But I think anything could be possible..., so I'm trying to apply the Maclaurin expansion. :roll:

Dear
If it's impossible can this be proven ?
when
(F/B)^(?*cot?) = (2?*P*cot? + 2Y)/Y

to prove the same ?

Re: Algebra problem............?

seems no way too. I just wonder how the author put things together? :shock:

It could of course be proved from ${\small{(F/B)}}^{\mu\cot\alpha}\,=\,1\,-\,\,\frac{P}{Y(1\,+\,\frac{\tan\alpha}{\mu})}.$
