Prove c bisects angle between a and b | Vector Algebra

[QUOTE="Mark44, post: 4995540, member: 147785"] This doesn't look right. If θ is the angle between a and c, you should have ##cos(θ) = \frac{a \dot c}{|a||c|}##. When you substitute in c and |c|, there should be some stuff in the denominator. I don't see that in what you have. Yes. Absolute values apply to real numbers. For a vector, |v| means the magnitude of the vector. Regular multiplication, if I'm understanding what you are asking. The two quantities in parentheses are real numbers. [/QUOTE]
