Howdy folks, It seems I always forget my trig when I need it. Quick question: How do I calculate an angle in degrees given an x,y vector. The vector for 0 deg being {0,-1} 90 deg would be {1,0}; 180 = {0,1}; etc... atom angle sequence vector vector = {-0.38,-0.92} angle = ? thanks for any help, Lewis Townsend BTW is there a website that has all the math formulas, trig esp?
