Question
Find the exact value of the trigonometric function at the given real number.
Exercise (a)
sin(7)
Step 1
Recall that sine has period 27. We must first recognize that 7% is greater than 27, but is not evenly divisible by 2. Therefore, we can simplify by rewriting
7π as the sum of a multiple of 2% and a number less than 2*.
sin (7x) = sin(
