Let = + , =b1 +b2 + and = 5 + + be three sectors such that the projection castor of on is . If + is perpendicular to then is equal to:
Let = + , =b1 +b2 + and = 5 + + be three sectors such that the projection castor of on is . If + is perpendicular to then is equal to:
Projection of to on = =
b1+b2=2 … (1)
And ( + ( . =0
5b1+b2=−10 … (2)
From(1)and (2) b1= −3 and b2=5
Then =
