Best ResponseYou've already chosen the best response.1Yes, but we have to figure out the exact value. So, what I would do is convert radians to degrees first. If you let pi = 180, then you will have: sin(3(180)/4) = sin(3(45))

Best ResponseYou've already chosen the best response.1The only thing you need to figure it out is a unit circle. \[\sin(135^{\circ}) = \frac{\sqrt{2}}{2}\]
