is it possible to have vectors with more units than 2? sometimes I have to calculate vectors with values like 2i, 2j, and 2k, but i can't figure out if its possible in this function...

Thanks bro I thought my calculator was broken or something

[@maartjevankampen1706]

how can we add more than one vector? we are talking about forces in the engine and need to add up multiple vectors, in the last assignment it was 9 vectors. we can put them in the calculator but not add all 9 of them up..

Very nice job. Thank you.

[@EHbhuiyan]

Glad I could help!

Fantastic!!!

Is "R" the distace of the vector?

[@omrahn8906]

Can the program do z coordinates as well?

[@EHbhuiyan]

I don't believe so. However, it may be useful to use the matrix option for vector operations. The calculator can do matrices.

That’s what I also need like in 3d coordinate system did u seem u figure out thatv

how did you get those apps

[@EHbhuiyan]

They were already on the calculator. However, if you don't have them, you can download them from Texas Instrument's official website and transfer them to your calculator. By any chance, are you only seeing the "finance" app when you go to the app options?

@@eddiehallo5051 Sometimes the apps get deleted (perhaps you accidentally did something). Before trying anything complicated, I would recommend checking if there are any programs installed that may be causing this problem. You could have installed a program that caused the apps to get deleted. Check/ Clear the programs: 1.) Press the button labelled "prgm". That should display "exec," "edit," and "new" in one line. If there is anything underneath that means there is a program on there. 2.) If there is a program, press "2nd" and then "+" 3.) Select the option labelled "Mem Management/Delete" 4.) Then select "prgm" from the drop-down list that comes up. 5.) Press "enter" to select the desired program to delete. Once an asterisk appears, press "delete." 6.) Confirm you want to delete by choosing "yes" If that doesn't work, you might want to try one more thing before going on the Texas Instrument's site to download the apps. Try garbage collect. Garbage collect: 1.) Press "2nd" and then "0" (selecting catalog). 2.) Press "tan." 3.) Press enter to select "Garbage Collect" 4.) Press enter and confirm with "yes" See if this works. Otherwise, what you may end up having to do is hook up your calculator to the computer to go on texas instrument's website and download the app and transfer it to your calculator. education.ti.com/en/products/calculators/graphing-calculators/ti-84-plus-ce?keyMatch=ti-84+plus+ce&tisearch=Search-EN-Everything&category=applications
