I am trying to make a program where if I plug in the number for systems of equations, it will find the intersection point for me.Example:ax+by=c; 2x+3y=0 dx+ey=f; -2x-y=4(-3,2) would be the intersection point.What would I have to do for the calculation part?I'll first use input and make the user put in the values for a, b, c, d, e, and f.I know how to do solve systems of equations in many ways, but I don't know how to program them because for example if I want to say-2x/3 -> yIt won't work because x isn't defined I think....I've been trying to make it work, but my head is about to explode now!
Then what should I do if I run out of battery? So from what I read and experienced just now, I can't run or edit the program while it's archived, it said "ERR:ARCHIVED" for me. So with the programs I'm working on, it'll probably be in the RAM meaning if the RAM cleared, the program would disappear. Every time my battery went out, and I put in a new one, it says RAM Cleared or something like that.... is there a way to make the RAM not clear when I renew the battery or something like that?
I really really need help on this please!!!!All my programs disappear every time the RAM resets or clears!How do I make that not happen or maybe save it?
I found it!!! Step 3 didn't really help.I thought you were supposed to press on PRGM from the home screen. I didn't know you were supposed to press on PRGM from the EDIT PRGM screen. I found out because I was looking at the advanced instructions about changing the name of the PRGM and I was following the steps and ended up at the screen. Thank you for all the help!!!
I have another question, in the programming editing screen, how do I delete the extra lines if I pressed enter several times?I mean like how do I delete the colons.:Disp "HELLO WORLD::::how do I delete those four ":" below the first command?
I don't see how step 3 helps... I still can't find "I/O" or "CTL" after reading step 3.Step four says:Step 4: Hello worldNow you can edit the program. The first thing we are going to do is press prgm, go to I/O and choose Disp (or press 3). Now type "HELLO WORLD". Do not forget the quotation marks! Your screen should look like this:I don't know where I/O is so.... i can't go to it....Step one says:Under prgm you'll find three tabs: CTL, I/O and EXEC.but I can't find itPlease help! :(Do I need a silver edition?But in the picture, it's a TI-84 Plus in step 1
Help please!!!!!!!!!!!!!!!!!!!!!!I have a TI-84 Plus and when i go to PRGMthere's: "EXEC" "EDIT" and "NEW"i can't find "I/O" or "CTL"!!!!
