To solve this problem you must apply the proccedure shown below:
1. You want to express Cos(7π<span>/3) as a trigonometric function of an angle in Quadrant I. Therefore, you have:
2. You can find the coterminal angle of </span>7π/3 by substract 2π, as following:
=7π/3-2π
=π/3
3. Then, you have:
Cos(7π/3)
Cos(π/3)
The answer is: Cos(π/3)
Okay, my prior answer got deleted for no work, apparently.
I'll re-post it though.
That word problem translates to:
I think that the first person who came along to buy apples would have to buy 12 dozen apples at $1 per dozen. Paul’s sells one dozen, Nick sells 4 dozen, and Ben sells seven dozen. After that, Paul has 3 apples, Nick has 2, and Ben has 1. If they all sent their remaining apples at a price of $3, Paul would earn 9 more dollars, Nick would earn 6, and Ben would earn three. That puts them each with a profit of $10.
