If the radius of a circle is > 1, coordinates on the circle can be greater than 1 or less than -1.

Yes, the tests are aren't printing the tested values and expected results. The most likely problem is rounding. I'll try and get the tests fixed so they print out what they are expecting. I'll see if I can add some random tests as well. Thanks.

On the Java version, when I run the tests, I see the text result without any actual number values. Something like this, "Expected: Received: " No test values are displayed, either. Is this likely due to something I'm doing wrong, or a problem with the test cases? Interestingly enough, my code does pass the initial tests, but on the subsequent batch, there are some failures. None of them, though, display any actual values on the results. Any ideas?

Thanks for the kata! Description 3rd line contains a typo in the word function.
