Chapter 7.4, Problem 4E

We can find the solutions of $\sin x=0.3$ algebraically.

(a) First we find the solutions in the interval $[0,2\pi )$. We get one such solution by taking ${\sin }^{-1}$ to get $x\approx$_______. The other solution in this interval is $x\approx$_______.

(b) We find all solutions by adding multiples of ______ to the solutions in $[0,2\pi )$. The solutions are $x\approx$_______ and $x\approx$_______.
