2. Note WebAssign HW 2.1 I Exam 1 Next Friday. You need to make sure you have an approved calculator.

3. 1.4+1.6=2.1? Section 2.1 For the graph of y=f(x), the slope of the tangent line at x=a is (Moving objects) For the position function, y=f(t), the instantaneous velocity at t=a is For a function y=f(x) (without geometric or physical contexts), the instantaneous rate of change at x=a

4. 1.4+1.6=2.1?

5. Section 1.6 We use algebra to compute limits Section 2.6 We compute limits such as the slopes of the tangent line and the instantaneous velocities
