help with Instruction() - Angus - 02-25-2015 11:43 AM
hi everybody!
I need help with Geometry.Instruction().
Reading from the list works fine, but doing
Geometry.Instruction(0):="plotfunc(x^2,x)" fails with error Invalid input.
f(x):=x^2/4;
Geometry.Instruction(0):="plotfunc(f(x),x)" fails with error Invalid Input.
edit:
I remembered Han's comments on strings as parameter in CAS commands in a program. So I tried
cmd:="plotfunc(x^2,x)
Geometry.Instruction(0):=cmd which also gives an error
How do I use that command to ADD a String to the list?
