Question
Let P = (0, 1, 0), Q
Recall that a vector of the form
=
w = t₁OP+t₂00
(0, 0, 2), and O = (0, 0, 0).
is called the linear combination of OP and O. What can you say about w
under the following assumptions?
If t₁ + t2 = 1? ¹
If t₁ + t₂ = 1 and t₁ ≥ 0?
If t₁ ≥ 0, t₂ ≥ 0 and t₁ + t2 ≤ 1?
Hint: the line passing through P and Q can be described by
OP + tPQ = OP + t(OQ – OỈ).
