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?
