Ok math geniuses solve this equation

[Bird222]

Solve this equation on this site http://www.investopedia.com/articles/03/101503.asp#axzz1qQvOZthD (about 2/3's down the page) for 'i'. It's the 'present value of an annuity due' formula.

No.

What do I win?

 

[WaTaGuMp]

Over 9000

 

[IronWing]

i = 0.05

 

[SandEagle]

No.

 

[repoman0]

Not possible to solve for i in closed form - do it graphically!

Read the end of the article OP .... Present Value Annuity Due Calculator

 

[Bird222]

i = 0.05

Sorry maybe I wasn't clear. I would like the formula rewritten with 'i' by itself on one side of the equal sign.

Edit: Derp.
I can read posts more gooder now.

Oh. That's harder.

won't wolfram alpha do this? but you need an account and i'm too lazy to make up personal info.

You can use binomial series to solve for i. Although I am not sure of it myself.

1 and -1 gets canceled.. and after you divide the rest with i(denominator) you'll be left with and expansion n+n(n-1)i/2!....

 

[darkewaffle]

Do your own damn homework.

 

[sactoking]

IIRC it's stupid to solve for i, everybody just iterates. Hell, even financial calculators iterate to find i instead of solving.

 

[SphinxnihpS]

Calculations such as these lend themselves better to Monte Carlo.

pfft. the answer is 42. The answer is ALWAYS 42. So long, and thanks for all the fish.

Why? They are giving you the interest rate (i), as well as all of the other variables. The equation's solution depends on them giving you at least two of them. What is your point?

I thought the ultimate questions was "Is she the One"?

I am not looking for a specific answer. I was wanting the general formula rewritten for 'i'.

Not happening.

So does that mean there really is no way to rearrange the formula for 'i' then?

More likely there's no way you're going to get anyone to do your work for you for free.

$4000 + $545 + $0.95 = i
