Please execute the "ver" command. You should have something like
Symbolic Math Toolbox Version 6.1 (R2014b)
as part of the output. If not, that is the answer, you do not have the Symbolic Math Toolbox. If you do have, let's see what
which syms -all
returns

You don't have a license to the Symbolic Math Toolbox, so there's nothing else we can do to help you. If this software is required for your homework, then I suggest talking to your instructor or fellow students to learn how to obtain the required software for your course.
