[edit] Neper's circle

I corrected the image for Neper's circle

I corrected the image a bit more. The original figure was mismatched with the description of the equations given in the text. The figure, as it was previously drawn was similar to the one on the referred page: http://www.rwgrayprojects.com/rbfnotes/trig/strig/strig.html. The equations as stated in the wiki article are the co-equations of this page. So either the equations need to be corrected, or the picture needed to have the complementary angles drawn. I chose to fix the picture.
