In each of 1 through 4, transform the given equation into a system of first orderequations.. u + 0.5u + 2u = 0

L6 - 8 What do we mean by making f(x)a ri eto L x − 1 Consider our function f(x)= x − 1 ,x =▯ 1: 2 We write lim f(x)=ml x − 1 = x→1 x→1 x − 1 To show that lim f(x)=ml x+1=2,w em ustshwthat x→1 x→1 |f(x) − 2| becomes arbitrary small when x is suﬃciently close to 1 (but x ▯=: |f(x) − 2| =
