Hello,

for my examination in electrical engineering, I have to save 150 mathematical formual in my Class Pad.
Im not sure of the right way to put in the formula.
Programm
or
eActivity
or
Spreadshett
and so on


Lg= L1 + L2 + L3 + L4


Pzu1*(Lg-L1) + Pzu2*(Lg-L1-L2) + Pzu3*(Lg-L1-L2-L3)
Pa= -------------------------------------------------------
Lg
Input: L1 ....L4 (L x)

Input: Pzu1...Pzu3 (Pzu x)

Output: Pa



Are any able to help my, please send me operating intructions to put in that following formula example.
I hope to hear soon, and thanks for you help.

With kind regards from Germany

i would write them in differents eactivities regarding the concerned chapter, and at the top of each page add a elink to "main" mode : you can see all formulas and you can calculate easily.

I think you have to write some simple functions in Library folder.
Use the Program Application.
For example you want to store :
V = RI

Folow these instructions:
1: Tap on the Program Application in Main Menu
2: Tap on the New Icon in toolbar and choose Function from top scroll bar.
3: Select Library folder form folder scroll bar then tap on OK.
4: In editor box enter a name for your formula (such as Voltage)
5: In front of functuon name enter parameters (I, R)
6: In main edit box type your formula (V*I)
7: Store your function and then you can use it in main application.

If you have some problems, you can refer to your classpad guid.

Good lock.

some of the guysatmy university (and me too) needed some of these formulas too, we've done the way Overlord discribed.

Write an eActivity with a main thing in it. (you can input the formula once and then copy it in the main thing)

An warning: Don't use r1, r2, ... in your formulas (we got errors) - use s1, s2, ... or something like this instead.

I like electronics too, i made 2 programs for the classpad about electronics. Also i hope i will start programing my classpad again the next vacations (i will finish my studies then i will not have nothing to do in the nights), hope i will have a nice project to do.

i would write them in differents eactivities regarding the concerned chapter, and at the top of each page add a elink to "main" mode : you can see all formulas and you can calculate easily.


@Overlord: Nice i would like to watch that. Also i can add some formulas, but right now i have some lack of time. If i can download your programs/e-activities please tell me the URL i'm interested on it.
