Question

Let vectors u=<2,-5,-1> , v=<-1,4,0>

write vector v as the sum of two nonzero orthogonal vectors, one of which is a scalar multiple of u

Answer 1

are you learning vector projection?

Answer 2

yes, it's a linear algebra question

Answer 3

project v onto u
that's one of your vectors... the other is v minus the projection...

Answer 4

How did I not think of this? lol Thanks a bunch :)
