The HP15c always surprises me regarding how cleverly distributed the keyboard is, and how well thought out is the function set. It is a long program but it makes use of many of the programming techniques in the HP15c. for that I have entered several financial programs including the Time Value of Money program.
This week I have been using the HP15c in my normal work. I will give it to him with the leather case to increase the acceptance rate - by the way! I guess that the Prime will not see much use after he has finished college! He'll have one as heritage, and he'll be thanking me for it in the long run. I plan to have him learn how it really works.

Plus, it is small enough to be really portable and carry it on your jacket pocket and it keeps the utter elegance of the HP50g we were discussing about. I see no point in having him using a HP41, even the cel: is a cumbersome machine that will occupy a lot of room in wherever he puts his things The hp42s would be an alternative, but even that one is a little too big but the HP15c is exactly the right size and has everything the prospective engineer needs - short of anything a computer spreadsheet or Mathematica or Mathlab can do. My discussion with him versed on the fact that the HP15c is the best calculator to master "for the rest of his life". I hope that my children never see it or there goeas another distraction more) You can take a look at the games that have been programmed with it in. (It is surprising what can be done with this language. I have the feeling that the HP50g is the better calculator, due to its more "elegant" programming model however, the Prime has more raw power and is easier to program is a procedural language similar to basic. Probably it is the best calculator for a student nowadays. He's just finished the first year, and he's very happy and thankful of having the HP Prime calculator. I am having a discussion with my son, an engineering freshman. This of course might be done easier with the HP15c – where you just need to enter the polynomic expression as a RPN program and then apply the generic solver. Now, the calculation will give you a zero you need to play with the initial values of r to find others. Be careful of the discontinuities that may happen when i crosses zero. Then you just have to find X substituting again.
Careful with the monthly/yearly equivalences!. You just have to enter the coefficients as period cashflowsand the constant term, and solve for interest i. You can now find the zeroes of the function. What the calculator does it trying to solve the NPV equation for r: getting the internal rate of return (IRR)īut if you replace 1/(1+r) = x, you have a polynomic function in x. It misses trigonometric functions, integration, solver…ĭoes it really miss a solver? It does miss a generic solver, but it does have a solver for the NPV calculation. The HP12c is maybe the perfect financial calculator, but it is quite limited when it comes to scientific purposes. I have not read it from a long time ago, but I got struck by it sheer originality.
