Question

3pi/2 - 4pi/2

Answer 1

Here is our expression:
\[\frac{ 3\pi }{2 } - \frac{ 4\pi }{ 2 }\] Since we have the same denominator, we can simply subtract the numerators and get:
\[\frac{ 3\pi - 4\pi }{ 2 } = \frac{ -\pi }{ 2 }\]

Answer 2

thats what i get also but thats not a answer choice

Answer 3

If we're talking about angles, the angle -pi/2 is equivalent to -5pi/2 because subtracting 4pi/2 is equivalent to a full revolution.
