Re: HP42S, Need TVM Programs? Message #2 Posted by Andrés C. Rodríguez on 14 Nov 1999, 6:27 p.m., in response to message #1 by Rafael J. Diaz
In the HP 42S manual, chapter 12, there is an example. Otherwise you may try programming the TVM equation for the solver. The equation is: 0=PV+(1+i*b)*PMT*((1(1+i)**(N))/i)+FV*(1+i)**(N) where N,i,PV,PMT and Fv are the usual TVM variables, b is 1 for begin mode, b is 0 for end mode. I used the ** symbols to denote "power", since the forum does not allow too much for formatting To clarify this, in my notation 3**2 = 9. So the **(n) means raising the previous expression to the negative nth power.
