2. Example-2





1. Find 3×A
`A=(5,-1,1)`


Solution:
Here `vec A=(5,-1,1),vec B=(-2,3,4),vec C=(5,-1,1)`


`3 * vec A`

`=3*(A_1,A_2,A_3)`

`=(3*A_1,3*A_2,3*A_3)`

`=(3*5,3*(-1),3*1)`

`=(15,-3,3)`
2. Find 2×B
`B=(-2,3,4)`


Solution:
Here `vec A=(5,-1,1),vec B=(-2,3,4),vec C=(5,-1,1)`


`2 * vec B`

`=2*(B_1,B_2,B_3)`

`=(2*B_1,2*B_2,2*B_3)`

`=(2*(-2),2*3,2*4)`

`=(-4,6,8)`
