Answer:
Step-by-step explanation:
Angle of 9pi/4
The equivalent angle of , on the first lap, is found subtracting this angle from
. Thus:
Thus, the sine and cosine are:
Angle of 3pi/2
On the first lap of the circle, thus no need to find the equivalent angle. We have that:
Expression:
Considering that
