Best ResponseYou've already chosen the best response.06a + 8b = \[\left u \right\] (10)(1/2)

Best ResponseYou've already chosen the best response.0by theorem 3 we need u * v = \[\left v \right \left u \right\] cos 60

Best ResponseYou've already chosen the best response.0if we know that u is a unit vector then v * u = vcos 60 if you unit vector v then v*u = cos 60 that how I think of it...

Best ResponseYou've already chosen the best response.0no i didn;t multiply everything by 64 100a^2 60a 39 = 0 a = .3928, .9928

Best ResponseYou've already chosen the best response.0then i need to plug those back into 5/8 3/4a to find b right?
