As long as you do the math for the angle between planes, you might as well show the equation for the line, or a point on the line.

Thank-you. I teach calculus and just found your site. It is super time consuming so that I don't have to manually check 25 different solutions!

Hello,

I am currently teaching geometry at the University of Liège, Belgium. I found your site when I was looking for a standard notation for the angle of two vectors. Your formula for the angle is correct. However, maybe you should mention that it holds for non-zero vectors and adapt the calculation accordingly. For the vectors (0,0,0) and (1,2,3), it returns the value 0, although the angle is not defined.

Best regards,

P. Mathonet
