Best ResponseYou've already chosen the best response.1it is vector notation. the () are equations to calculate the scalar functions of each vector; hence(1t) and (t) cahnge the size of the arrow that represents each vector..

Best ResponseYou've already chosen the best response.16<2,3> is an arrow from the origin to a point (2,3); the scalar says to multiply those values by 6 in this case... <6(2),6(3)> = <12,18>which is an arrow from the origin to a point (12,18)

Best ResponseYou've already chosen the best response.1(1t)<2,1> means to scale the vector by whats in the (): <2(1t),1(1t)> = <2+t,1+t>

Best ResponseYou've already chosen the best response.1vector t<1,2> is scaled to : <1t,2t>.... now add the vectors together
