2 Question 1 Clearly circle True or False. No need to explain. a) True / False , 2 ! , ln 1, exp(1) are all irrational numbers. b) True / False | | x x + is nonnegative for all real number x . c) True / False By L x f c x = ! ) ( lim we mean that, for every 0 > , there is a corresponding 0 > , such that " < # \$ < # < | ) ( | | | 0 L x f c x . d) True / False If ) ( c f does not exist, then ) ( x f is not continuous at c x = .

How should f be defined at 0 = x in order to make it continuous there? b) Show that the equation 0 10 2006 12 16 = ! + x x has a solution in ). 1 , 0 ( Space
3 Question 4 Determine the derivative with respect to x for the following functions, a) f(x) = (tan 2x) 3 b) g(x) = (x 2 - 2)/(x 2 + 1) c) USING the limit definition of the derivative show that D x (x -1/2 ) = -(1/2)x -3/2 Space Question 5 A circular cylindrical oil drum of length 1m is lying on its side. It contains diesel fuel but has a small leak at the base so that fuel is leaking at a rate proportional to the depth of fuel remaining in the drum (i.e. dV/dt = - k a h, where V is volume of fuel in m 3 , h is the depth of fluid (in meters) in the drum, a is the drum radius (in meters), and k is a positive constant with units of m/s). Using the notation in the diagram, a) Obtain expressions for the depth h and volume V of the fuel remaining in the drum in terms of the angle θ and the radius a. These should be valid for 0 θ π . b) Determine the rate at which h is changing (i.e. dh/dt) as a function of a, k and θ . c) Rearrange to give dh/dt as a function of a, k and h. Space top of fuel θ h a
