so it is e^(pi*2n*i)-1=0
while e^(pi*(2n+1)*i)+1=0

could somene please explain the proof behind bringing numbers to imaginary powers?

Think about how you would do something like raising something to an imaginary power :D You can set up ratios and stuff and do more stuff and stuff. Also, e^(ix)=cos(x)+isin(x), so 3^i would be cos(ln(3))+isin(ln(3))

EDIT: so you can say with that the idea that e^(i2pi)-1=0 (that is i times 2 times pi)
so what you are saying is that e^i*n*pi)-1=0 where n is any natural number(possibly negative)

this is confusing could someone please explain how you bring numbers to imaginary powers and why you do it that way. I did not think you could bring a number to two separate powers and still have them equal the same number

I prefer the Ti-Nspire Non-CAS color scheme than this. I don't like all black. this looks amazing, I might even get one if TI doesn't overprice it like everything else they sell. I am wondering about Camdenmil's worry. It doesn't appear to have a seam anywhere for the TI-84+keypad to go in. I wonder with the calculator color will they adapt the TI-84+ to be color also?

I have one request I would like you to add in. Could you add in something that lets you press a button to exit mid-video? I know that is on many other ndless programs. I could use this for the middle of math class...

I actually found that the easiest way to solve this problem was to save the file as a microsoft 2003 file then print. I guess it was because it saved it as images instead of math zones.

There is no print preview it automatically shows it right next to the print screen. It shows all the math zones in the print preview. could It be a problem with my printer?

I have been attempting to write a math book in Microsoft word. I have 2010 and the Mathematics add-on. When I try to print it off it prints just every math equation i added in is left out but there is space for them ??? does anyone know why this is happening. I would like to be able to go over this/write more at school but I would like to be able to see what I've done so far to do that. thank you for any help you might give

Yes but It won't let me load any programs to it so it kind of sucks.
