# Math Help - Sine

How can there be two answers then? because of where the curve crosses the x axis?
Sine is positive in the first and second quadrants.

The solution the calculator gives you for $\sin^{-1}{0.6}$ is the angle in the first quadrant.

To find the angle in the second quadrant, subtract what you have found from $180^{\circ}$.

2. For the function: y = sin (x) the graph crosses the x axis 3 times from 0 to $2\pi$
$2\pi$ = 360 degrees

For y = sin (x) - .6 the graphs shifts down .6 which makes decreases the area above the x axis and increases the area below the x axis and in turn changes where it intersects the x axis. Look at the attached graph and see if it helps.

3. Molly:

What an excellent reply, that has really helped a lot!

Thank you so much!
