Functions (trigonometric) (cloned)

Trigonometric functions

Are you good enough with trig functions to do great on the AMC?

In order to answer “yes,” you should know all of the following, without any hints or prompting:

• the double-angle formulas for $\sin$, $\cos$, and $\tan$
• the sum and difference formulas for $\sin$, $\cos$, and $\tan$
• what the graphs of $\sin$, $\cos$, and $\tan$ look like

What to do

• If you answered “yes” above, then this section should be straightforward for you. Click “complete” below, and we’ll add all the relevant quizzes to your deck. Then, during your short daily practice, we’ll occasionally quiz you on this knowledge in a way that etch it into your memory for good.
• If you answered “no” above, or weren’t so sure, then you can still click “complete” below, and add it to your quizzes, but I recommend against adding anything else for today. Instead, work with these new cards for today, and consider adding more fresh knowledge tomorrow or later.

Now continue onto your drills by clicking Quizzes in the menu on your left.
