# Quiz 2

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 $-\frac{4}{5}$.
