In addition to the weak test suite: The title of the problem says "Sinus function", yet the (incomplete) problem description mentions only "cosine" ??? Furthermore, should abs(cos(-x)) be assigned to y, or to z?
The test description has been updated. Also, new and improved test suites are added within the scope of the problem.
Please improve the test cases. Returning 1 and -1 is complete enough with these sloppy tests.
