In the test suite, the correct answer should be (1+sin(x))./cos(x)+cos(x) ./ (1+sin(x)) % note the dot-slash in the second term
Well, at least if we assume that it was meant to be consistent with the problem statement :)
Note that this problem uses the word solve when it needs to say EVALUATE.
I support John D'Errico's comment: equations can be solved, but expressions cannot.
Also, it is pointless having the solution method exposed in the Test Suite. See further discussion at Problem 44617 &c.
