Question 364496: Evening All, Stuck on this vectors problem.
a) In cartesian coordinates, the vector a has cartesian components (4,-2,3) and the vector b cartesian components (-2,3,1). Express a nd b in terms of the unit vectors i, j and k.
Find �a�, �b�, a, b and 3a-2b
b) Given a=6i+2j+k and b= -i-4j+2k, express a and b in terms of Cartesian components. Find �a�, b�, a, b and 2a+b
Thank you for your time
