Code of honour: I am trusting that you are all not cheating for this exam. You are more than welcome to use the notes from class to help you answer the questions (in fact, I encourage it!) But please don’t talk to one another nor should you use the internet to ask for solutions to the problems. I trust in you all.
Exercise 4 Differentiate the following:
Exercise 5 (10 points) Suppose that s is a function of r. Find d/dr s of the following function:
r4s2 + sin(rs)2 + csc(r + s) = 5
(Bonus - 5 points) Suppose further that r is a function of q. Find dqd s2.
A 2 meter tall bear is walking in the woods and sees honey flavoured chips strapped to a flashlight hanging from a tree 3 meters above the ground. The bear, smelling honey, decides to raid the chips package and starts walking towards the honey at 3 meters per second. As the bear walks, the flashlight is casting a shadow behind the bear which gets shorter and shorter.
(1) When the bear is 3 meters away from the honey, how fast is the length of his shadow decreasing?
(Assume that the honey chips and the flashlight are at exactly the same point.)
Exercise 7 (5 points) Find a good approximation for
f(x) = arccot(x) at x = 8/9
Exercise 8 (20 points) Using the techniques in class, sketch the curve of the following function.
f(x) = x3 − 18x2 + 81x
