Hello, I have this little math problem. I have this formula from wich I get a dot product between two vectors.
cos(ß) = A.B / |A|.|B| = -0.0634 So this would give me radians, right? Then if I use math.degrees( -0.0634 ) This gives me a value of -3.6325524211294193. However I have a book in front of me who says I should get a value of 93.635 degrees. mmmmm Btw, in the book, the equation is written ß = cos-1(-0.0634) = 93.635, where -1 is actually an exponent. Maybe I'm just interpreting this wrong? Thanks Bernard _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
