calculus help needed
example: sin1(1/2)
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.
