• $\text{When sketching }y=2\cos x\text{, which feature of the graph changes?}$
  $\text{The amplitude (vertical stretch).}$
• $\text{What is the first step to sketch }y=\sin (x+30^{\circ })\text{?}$
  $\text{Start with the standard }y=\sin x\text{ graph and translate it.}$
• $$\begin{gathered} \text{True or False?} \\ {\sin }^{2}x\text{ is the same as }\sin (x^2)\text{.} \end{gathered}$$
  $$\begin{gathered} \text{False} \\ \text{Correct Answer: }{\sin }^{2}x=(\sin x{)}^2 \end{gathered}$$
• $\text{What is the period of the function }y=\tan x\text{?}$
  $180^{\circ }$
• $$\begin{gathered} \text{True or False?} \\ \text{The graph of }y=\tan x\text{ has asymptotes at }{0}^{\circ },180^{\circ },360^{\circ }\text{.} \end{gathered}$$
  $$\begin{gathered} \text{False} \\ \text{Correct Answer: Asymptotes are at }90^{\circ },270^{\circ },\dots \end{gathered}$$
