v Exercise 1 Find the critical points of the function x) : 921/301: 4) by hand,writing your answers on paper, and inserting them as an image here. (You can do this on paper and then insert the image here in the usual way, in place of this text.) v Exercise 2 Use SymPy to check your answers from the previous problem, and verify that you get the same answer in software as you did by hand. Replace this text cell with code cells containing your answers. v Exercise 3 Find and classify all the extrema for the function in the previous two problems, when considered on the interval [0, 6]. You can do it by hand or using SymPy, whichever you prefer, but be sure to clearly state what your nal answer is in any case. (You can do this on paper and then insert the image here in the usual way, in place of this text; or instead you can replace this text with code cells if you plan to use SymPy.)
