calculus help needed
how do you figure this out?
The sin^-1 means the arcSin, or the angle whose sine is ...
so sin^-1(1/2) is the angle whose sine is -.5, which is -30 degrees.
In your calculator, put in -.5, then press INV sin.
so as my answer do i put pi/6?
That is the answer in radians. It should be negative. There is an angle in the third quadrant that yields a sine of -1/2 also.
