Math Problem

what is i? imaginary number? interest rate?

i is the yield % pa divided by 200

so yea...call it the interest rate

DeanPortmanTrying to do this for future valuation, can anyone help?

I need to get 'i' on its own

P= (C(1-v^20)/i) + 100v^20)

v = 1/(1+i)

stay up homies

Didn't you miss a parenthesis in the first equation?

The only way I see it being done by hand is:

using binomial approximation, so (1+i)^20 = (1+20i), if i is close to 0 (which it should be, if you consider yield % / 200)

But then again this is only an approximation, and I am not sure thats what you want.

edit: I can plug it into my laptop to get an exact result a bit later, if this still remains unsolved.

ok so your parentheses dont match in the first term but anyway...

i = C(1-v^20)/(P-100v^20)

i = (1/v) - 1

was that all you wanted? that was like 5th grade algebra

thats the problem...V is a function of i and I cant figure out how to get i alone, if its even possible

idc if its dumb or whatever or 5th grade algebra..im swampe

WHERE

v = 1/(1+i)

Maybe you could explain the specific problem you are having trouble with, there might be a way to do it without expressing i.

Or is that all you want?

I on its own is all I need lol. It's just aussie bond future valuation

Not solvable. This is a subset of math called Group Theory.

Anything over(I think) 6th degree is impossible to solve analytically.
