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

can this is done without using the calculator??

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.
