Re: TIB: Need help with math prog I am writing (BJE)




The dot product:

if a = (a1,a2,a3) (splitting the vector into its component 
   -		parts)

if b = (b1,b2,b3)
   _


then a.b= (a1*b1) + (a2*b2) + (a3*b3)....  
     - -	

of course, you can have many parts for the components, but 
we usually use three.

Please post any vector program, as i am just starting 
this at uni. :)

And, is there a way to plot points in (x,y and Z) on the 
calc...you know, a 3d plotter thing. That would really 
usefull (i have a TI-83 by the way!)
