Common Mistakes:

- (Section F) When you use the Intermediate Value Theorem, also known as Bolzano Theorem, make sure you mention the continuity of the function.
- (Section G) Only 2 students succeeded to give a full solution to the first problem, which makes me deeply sad. Notice that if \cos x = \frac{3}{5}, \sin x can be \frac{4}{5} or -\frac{4}{5}.
