We have that
y=sin O
for O=270°
find the value of sin O

we know that
270 degrees --------> convert to radians-------> is equal to 3pi/2

using a graph tool
see the attached figure

the value of sin O for O=3pi/2 is -1

the answer is
-1

Refer to the image, the 270 degrees corresponds to 3/2 pi.

Based on the graph, the value of sin(270) is -1.

So, the answer is -1.
