WebWe prove the following limit law: If lim x → af(x) = L and lim x → ag(x) = M, then lim x → a(f(x) + g(x)) = L + M. Let ε > 0. Choose δ1 > 0 so that if 0 < x − a < δ1, then f(x) − L < ε/2. Choose δ2 > 0 so that if 0 < x − a < δ2, then g(x) − M < ε/2. Choose δ = min{δ1, δ2}. Assume 0 < x − a < δ. Thus, 0 < x − a < δ1and0 < x − a < δ2.
