Questions on operation of the worksheet

[compsystems]

Hello

1: How to select all the inputs/outputs worksheet?
ctrl+A select only the current line.

2: how to quickly clear list of variables without using the purge cmd?

purge(expression_A1,expression_A2, expression_A4, expression_A5, ...)

by pressing the button of a variable [expression_A1] [expression_A2] [expression_A4] [expression_A5] .. copy all the instruction without ( : symbol ) (variable = content) this generates a warning when pressing enter,
also it is important in some cases to copy only the content and in other cases only the name identifier, a flag that allows to make these three changes facilitates the use of the worksheet

Code : Tout sélectionner

hypothesis_A:=[areat=z^2/4, areat=(x*y)/2, z^2=x^2+y^2  ]
expression_A1:=subst(hypothesis_A(2),hypothesis_A(1))
expression_A2:=subst(expression_A1,hypothesis_A(3))
expression_A3:=expression_A2*4
expression_A3:=simplify(expression_A3)
expression_A4:=expression_A3-2*x*y
expression_A4:=simplify(expression_A4)
expression_A5:=factor(expression_A4)

You can select levels, click on the first level and shift-click on the last levels.
You can restart a session with the command restart(). Or make a new fresh session of course...
