Supose that in this case the range were expresible in the form:

[-tan(tan(7)), +tan(tan(7)]

while this may numerically be a different range depending on whether we are

in degrees or radians, the most elegant form of the answer does not care

two hoots about which angle mode we use.

A more interesting question about this problem might be what is the domain?

There are two natural assumptions one could make for the domain, and they

are**R**and**C**. Each of these assumptions gives rise to a different answer,

and each is equally plausible as a guess at the setters intention. If I were

solving this problem I would solve both of these possibilities.

Yes I did, and it agrees with what I think the solution for the real

domain should be. However I'm not the setter of this problem, nor have I

discussed it with him so I don't know what he thinks a correct solution would

look like
