Given vectors b and c are they parallel? If so find such scalar s that c=sb, otherwise write N for no.
a) b=<0,3,4>, c=<0,6,-8)
b) b=<10,6>, c=<-15,-9>
c=sb is a property of the dot product.
The Attempt at a Solution
For a) I put No because <0,6,-8> does not = <0s, 3s, 4s> because S=2
For b) I put Yes because S=-3/2 which would give you both outcomes of the vectors
Am I correct?
