# Root vector

Vectors in geometry

### Root vector

maybe some one can help me in solving this root vector count.

Determined between two large vectors of equal area = F. When comparing between the magnitude and the magnitude of the two vectors is equal to the root 3, then the angle that forms the two vectors is?

Given a vector a = 3i-4j + pk and b = 2i + 2j-3k if the vector projection length a on b is 4 root 17 p value?
