An urgent question about variables
|
|
Hi,
I'm preparing for a presentation and it would make things much more clear if I could define some complex numbers as special values. In particular, instead of writing ((-1+i*3^.5)/2) each time, I'd like to just be able to type in w.
Likewise for u=((5+(-7)^.5)/2)^(1/3)
and v=((5-(-7)^.5)/2)^(1/3)
How can I define these variables so that whenever I create a function through Add Function, I can use these in my transformations, so that I could just type x*w rather than x*((-1+i*3^.5)/2)?
I've tried defining them using the Define a Function command, but I don't know if I'm entering the script properly. If if define w as ((-1+i*3^.5)/2) and then Define a Function as 5*w, the program evaluates this correctly, but when I try to use it through the transformation menu, it won't work.
Help!
Justin
