Answer 1

Hi:

try the following:

press the program key :
choose to edit or new program
For program name : Midpoint
or

goto apps key
select the program editor
select new

type for name midpoint

then type the following:

input "x1", a : { this is for x1}
input" x2" ,b : {this is x2}
input "y1",c : { this for y1}
input "y2",d { this is for y2}

(a+b)/2 store in midx { use your your calulator store key for this}
(c+d)/2 store in midy { part}

Disp "Midpoint = (",midx,",",midy,")"

End or return

This should do what you what. If not e-mail me at [e-mail] and I will help help you

I just bought one week ago, the same calculator, but I still didn't do any programing...Maybe you are older than me. I really do not need to program it. An advise: look on the Apps button, there should be something there, OR read that big thick manual of usage for the calculator.

How about looking in your manual? By the way, you aren't suppose to program formulas into your calculator to pass your test. Memorize!!!

Answer 4

If you actually *study* your book and *work* a couple of the problems with paper and pencil, the method of programing it will become obvious.

Of course.... By then you won't *need* the calculator ☺

Yeah if I recall right the plus is just the ti84 with a few extra features I highly doubt he would be too upset if you got the plus
