SECTION 3.3 SCALAR MULTIPLICATION: 2 = 1 2 Let u be a vector; let c be a scalar; and set v = cu. (1) If c > 0, then v is in the same direction as u. (2) If c < 0, then v is in the opposite direction from u. The length or magnitude of a u u = 1 22 vector 2 is uuu=+ 12 !"! Example: If uB= where A=(3, 4) & B = (5, -1), find u 2 u 4 −5 2 2 −=+ () ( ) =+=452 2 uc= (3) u 2u (-1/2)u The vectors u and v are parallel provided there is a nonzero scalar c such that v = cu. Given that u & v are parallel, 3 v = u = find a if and 2 So we know t
