Question

sin(3/2pi)

Answer 1

0.45952901044

Answer 2

how?

Answer 3

Answer 4

oh wait hold on mis understood the question

Answer 5

I don't think that's how I was supposed to do it.

Answer 6

do you need like a number value because of you do then all you do is plug it in
(3/2pi) pi =180 2pi=360

Answer 7

\[\sin (\frac{ 3 }{ 2 }\pi)\] im supposed to use a graph

Answer 8

The angle is in the 2nd quadrant and the angle of reference (always from the x axis) is 60 degrees. The sin of 60 is the square root of 3 over 2. And, since it's in the 2nd quadrant, it is positive. Remember sin is positive in the 1st and 2nd quadrant and negative in the 3rd and 4th.
So you should be able to use your graph now
