# Core 4 Vectors

Vectors have direction as well as size
The magnitude of a vector is the squared root as all the values squared eg : (4i,3j,2k). 4^2+3^2+2^2=29 so the magnitude is the square root of 29
Adding vectors - so add all the I parts then all the j parts and k parts and write it as a column vector
Subtracting vectors - take away the I parts from the other and the same for the j and k parts again write as a column vector
Parallel vectors are multiples of each other
Position vectors is a point from a fixed origin…
