## Subscripts in Functions...

Maple

How can I use subscripts in functions?  I can define an equation such as A1=B1+C1 fine.  But when I type in  A1:=(B1,C1)->B1+C1 , I get "Error, invalid operator parameter name".  What gives?  Any work arounds?

## Plot full x-axis...

Maple

I have a function that PLOT (2D) refuses to write all the way out to x=0.01 .  It stops the curve at x=0.005 or so, no matter how hard I try to make it do otherwise.  When I make a POINTPLOT from a SEQ generated from the function, then I see the full curve.  Can anyone tell me what is wrong before I send this problem in to tech support?  I am sure the function is defined and continuous.  Ratch

## Multiplication with Two Parentheses...

Maple

Why is it that Maple is smart enought to know that a term like 3w means three times w, but two terms in parentheses like (3+7)and (7+8) with no multiplication operator between them gives an answer of 7?  When a multiplication operator is inserted between the parenthesis, the correct answer 105 is obtained.
