The multiplication of each member of the equation by (1+i)^60 in minute 3:45 is unnecessary and makes the function much more complex.

[@charmanejantjies5052]

im so confused why did the first part of the derive's exponent change from 60 to 59??? this video made me more lost

[@maribelcervantes1830]

if you dont know why that happens, you probably shouldnt be studying this method with this application

[@smangasphelele4005]

He used a power rule method

[@complexcalculaton2931]

What are the other methods to find Interest Rate for different types of Annuity?

[@tz5starFx]

Can you solve with normal method to solve such type of annuity don't use raphson metho

[@ponah-v1001]

Nice explanation but ,Can't see the working out properly..those black writing is blocking us to see..

[@SUCC1NCT]

I think you made a mistake when plugging in the denominator in the Xn+1 function (i.e., it should be 48(1+Xn)^60).

[@ccluxi]

Yes I also think he made a mistake there

[@Larry821]

@@ccluxi Yes. Not surprising but correct formula converges faster (5th approximation is 10 decimal digits of accuracy). The wrong formula converges too , which might make these kinds of errors difficult to catch.

[@raulojeda8398]

Which method would you suggest for non equal installments?

[@federicoivagaza7662]

Thanks for the help.
if I add a new series of payment different from the one that already existed.
For example: $24000 is offered for payments of $450 per month for two years and payments of 600 per month for four years.
How do I solve this new problem?

[@Erick3000bc]

Did you figure out how to do that?

[@radnakse_mada]

Terima kasih bang

[@chynnekaragu4296]

Hi.. your video is very useful to me but when I apply this method to calculate this problem, at the end of each quarter a payment of $500 is made into an account which bearing interest compounded quarterly. If the annuity accrues to $7500 over three years, determine the nominal interest rate.
I didn't get the answer. Please can you solve this problem..
Thank you....

[@presidiun]

How does the method handle the cases where the interest is negative?

[@icmabtalukdar6189]

Sir is there any way to find out interest rate by using log ?

[@mmmwife]

hi, I try using your method to do my homework. But I got the monthly rate in increasing pattern instead. Is it okay or it should be in decreasing pattern? Because yours is in decreasing pattern.

[@ramayuliawan8492]

Why is x0 started from 1% sir?

[@MathematicsTutor]

You need to start from some value. 1% seems to be good value to take.
Thanks

thats easy
