Hello all. As these calculators are highly advanced, I found after wasting time and money on the HP 33s, I needed to buy one. For me, I like complex numbers...
Join the club. I see book everyday in Barnes and Noble or on Amazon which help owners of the TI 89 program or use all the basic functions. Until HP gets...
Hello dr, Using complex with your HP 50g is really easy, First thing you want to know is to toggle from real to complex, for this just press and hold...
... Hi Well, many thanks for the method. I will try that later. On the face of it it has simpified things. Still its a lot to remeber practice makes perfect I...
I was trying to use IFTE in RPN rather than algebraic, and can't figure it out On the stack, I assume I want - * Test value * Value to put on stack if test...
... I think I figured out my own error. I was running the program off the stack, but calling an incorrectly saved version in f(). In other words the program...
I have a followup question. Is there (in UserRPL) a way for a program to reference (run or RCL) itself if it is not stored in a variable? That would make such...
... rightshift (white) math, just below the down arrow. next (left arrow) cmplx c->r and r->c if you need to set the soft menu (not the drop down menu) shout...
I couldn't figure out how to change from the drop down menus to the soft menus. Here's the procedure I figured out: Convert from rectangular to polar or...
Soft menus are set with flag -117. Enter -117 and then SF and enter. Or use the flag browser by way of the MODE key. To do the conversion, set the mode you're...
The conversion from rectangular to polar and vise versa becomes really simple with the help of a little program that you assign to a key, I have it assigned to...
RPN MODE 'f(X)=X^2+1' DEF ADD f(X) on PLOT FUNCTION SCREEN (hold LEFT SHIFT + A) and press DRAW... 2009/5/25 rickwendel763242 <rickwendel763242@...> ......
Hello Rick, Once you defined your Function F(X), In RPN; Hold |left-shift| key and press |F1| for Y=, then press |F2| for ADD. Type F(X) and press |ENTER| . ...
To elaborate on my reply, you don't have to be in the mode you're converting from. Select the form you're converting to and just enter in the form you're...
Given an imaginary number representing the resistance (X) and the reactance (Y) thus providing a resultant (Z) and phase angle, can anyone figure out how two...
This is probably a stupid answer, but could you do a cross product of the 2 resultants? ... From: rickwendel763242 <rickwendel763242@...> Subject: [50g]...
I tried a couple graphs and couldn't come up with anything with cross products. I don't understand why two polar or rectangular coordinates are used to form...
The DROITE function has nothing to do with complex number theory, It's just an aid to get the equation of a straight line when you now two points that belong...
We both understand that the DROITE function is for that of a straight line. And I understand how to convert from Polar to Rectangular and from Rectangular to...
You press left arrow and pie, just below the 3 and it shows pie in the display and not the number. So, then it doesn't calculate with pie, it just shows it in...
type all your calculations and then use ->num to get the numerical value (right shift + enter) If you are in approx mode you can press eval as well (change...
