The magnitude of WX is ⇒ c
Step-by-step explanation:
The magnitude of XY (its length) where,
is IXYI =
∵ W = (-2 , 8 , -3)
∵ X = (1 , 4 , -1)
- To find the magnitude of WX use the formula above
∴ = -2 and
= 1
∴ = 8 and
= 4
∴ = -3 and
= -1
- Substitute these values in the rule above
∵ IWXI =
∴ IWXI =
The magnitude of WX is
