1. The problem statement, all variables and given/known data Given two vectors A=9i+1j+9k and B=12i-12j+10k find: a) Their dot product AB b) Their cross product AxB c)The angle between the vectors A and B d) a vector C that is parallel with A and has the same magnitude as B e) A vector C that is perpendicular to A and has the same magnitude as B 2. Relevant equations dot product: AB=AxBx+AyBy+AzBz 3. The attempt at a solution I got a, b, and c. a) (9)(12)+(1)(-12)+(9)(10)=186 b) 118i+18j-96k c) 42 deg. d and e) I have no idea how to get the vector to be parallel or perpendicular to A with the same magnitude as B. Just want a simple explanation please!
