And yet one more error:
the function arccos does not exist in Maxima. The inverse of the
co-sine is "acos". To make sure whether a function exists before you
try to use it, write the following in the command line:
? name-of-the-function
and press enter to see its documentation.
I'm glad you chose Maxima for your CAS homework and believe me: in any
other CAS you would have run into similar difficulties.
Cheers,
Jaime
