Hi
I am having trouble understanding what i am meant to do in the following question:

Find all values of x between 0 and $\displaystyle 2\pi$ for which
$\displaystyle sin x =0.6$

P.S

Use the symmetry of the unit circle: $\displaystyle x = \sin^{-1} 0.6$ and $\displaystyle x = \pi - \sin^{-1} 0.6$.

3. can this is done without using the calculator??

Of course. See my answer!

However, if you want a value of $\displaystyle \sin^{-1} 0.6$ then of course you will have to use a calculator to get a decimal approximation.

5. Once you have gotten you approximation which will be in degrees you need to convert your degrees to radians using:

$\displaystyle Degrees X Pi/180$

Then you'll need to write your notation.
