Homework Help: Math

Posted by HELP!!!! on Tuesday, April 2, 2013 at 5:35am.

If y = sin−1 x, then sin y = x,−π/2 ≤ y ≤ π/2.

Therefore, to find
y = sin−1(−3/22, we must find an angle y whose sine is -3/2.

There are many possible angles with this sine, but the range of
y = sin−1 x
is restricted to [ , ] and so y must be in this interval.
