Answer:
w-2u-v
Step-by-step explanation:
Given are three vectors u, v and w.
In R^2 we treat first element as x coordinate and 2nd element as y coordinate.
Thus we mark (1,2) in the I quadrant, (-3,4) in II quadrant and (5,0) on positive x axis 5 units form the origin.
b)
We have to find the values of a and b
]
Equate the corresponding terms
Divide II equation by 2 to get
Eliminate a
-5 = 5b: b=-1
a=-2
Hence
w = 2u-v
<u>To prove the trigonometric equation:</u>
We know that , substitute this in place of 1.
Multiply each term of the first term with each term of the 2nd term.
Group like terms together.
= LHS
RHS = LHS
Hence proved.
