Question

Could I get an example vector addition problem for practice?

Answer 1

Here you go:

If u = <a,b> and v = <c,d>, then u + v = <a + c, b + d>

For u = <-4,3> and v = <2,5>

Perform the indicated vector operation.

Problem one:
u + v

<-4 + 2, 3 + 5> gives you <-2,8>

Problem 2:

3u

So you have 3 times the vector <-4,3>; which gives you

<3*(-4), 3*3> which gives you <-12,9>

Try the three problems on your own.

Problem 3:

2u + 4v

Problem 4:

5(u + v)

Problem 5:

2u - 3v + 4u
