Hello!

How can I make a graphic of

I already made a post here, and it was well answered, but it was a function of 2 equations.
This is of 3 equations.

One possible method would be to make use of a CASE statement in a program for the various ranges.

I know you prefer algebraic mode, but I'm not sure how to use CASE that way. The following RPN/RPL program was created using algebraics, so perhaps it will at least give you an idea how to set this up:

Code:

\<<

   CASE

      'X<0' THEN 'SIN(X)' END

      'X\<=2' THEN 'SQ(SIN(X))' END

      'COS(X)'

   END

\>>

The resulting plot of this program looks like this when using default settings:
