38*75 = 2850 that is the answer
Question 2
Note: Let t = theta since I there is no theta symbol on my keyboard.
(0, -1) = (cos t, sin t)
cos t = 0
sin t = -1
I read the answer from the given point.
On the unit circle, the point (0, -1) lies at 3pi/2. So, angle theta is 3pi/2.
tan t = sin t/cos t
tan t = cos t ÷ sin t
Therefore, tan t = what?
You finish....
