For each pair of vectors, find U + V, U V, and 3U + 2V.U = -3i, V 5j

Chapter 2: Limits & Derivatives 2.2 The limit of a function We live in a world of approximation (e.g. a line theoretically has 0 width) lim fx)= fa ) x →a provided a is in the domain of f lim ex Ex1. x→−∞ =0 You can get this from drawing a graph. Ex2. lim 1=0 x→−∞x You can get this from drawing a graph. 2 E3. Consider f(x)= x +2x−3 x−1 x +2x−3 (x−1)(x+3) = =x+3whenx≠1 x21 x−1 lim x +2x−3 =lim(x+3)=4 x→1 x−1 x→1 x+3 x=1 The graph is the line with an open circle at Ex4. lim√x+1−1 =
