Exercice 1 We consider the function f(x) = 2 #0 and for r > 0. let S, = {€ C/2 = r} with positive orientation. For 0 < <R, we denote by r the curve consisting of SRUT-R,-€) US, UL, R), where S = {z E C/121 = } with negative orientation. 1. Prove that o = [513)dz = [5(=)dz + [s()de – [ (dz + 1" $(x)dr.
2. (10 pts.) Consider a sphere of radius R > 0 and its bounding cylinder with height 2R that is tangent to the sphere precisely in an equatorial great circle (as depicted below) Define the axial projection of the sphere onto the cylinder and show that the axial projection of the sphere onto its bounding cylinder pre- serves area. Hint: Given a point (ro, Vo, zo) on the sphere, the axial projection of the sphere onto the cylinder fixes the...

3. Consider the following piecewise function (a) Draw an accurate graph of f(). (b) As always, f(x), has an infinite number of antiderivatives. Consider an antiderivative F(r). Let us assume that F(r) is continuous (we don't usually have to specify this, but you will see in the bonus part of the question why we do in this case). Let us further assume that F(2) 1.
