um... for this question. I just don't get the picture and meaning of
a) C DOES NOT ENCLOSE THE ORIGIN
b) C ENCLOSES THE ORIGIN.
Could you please explain this to me maybe with a picture if possible ? Thank you very much.
Please don't show me how to calculate the second question because I have the solution for this question.
