1. Consider the following sentences: “You can approximate your instantaneous velocity at a point in time by finding your average velocity over a short interval containing that time. As you make the interval shorter, your approximation improves.” Now explain why this formula for instantaneous velocity makes sense: v(a) = lim h→0 f(a + h) − f(a) h
