find range: y= 1/2-sin3x

Note by Akash Sinha

Sort by:

$$y = \frac {1} {2 - sin 3x}$$ or $$y = \frac {1}{2} - sin 3x$$ ?

Anyway, for the first one, Range is $$(\frac {1}{3}, 1)$$

For second one, Range is $$(-\frac{1}{2}, \frac{3}{2})$$

Reason: The min and max value of $$sin x$$ is $$-1$$ and $$+1$$ respectively.

How do we find min. and max. values ?
