A rounded 5-sd set of solutions is
This represents the compounded oscillation of the separate
oscillations for sin x and 1.5 sin (1.5 x ) of periods
I have obtained one approximate solution from
This 5-sd solution
convergent root-bracketing (optimized bisection) method.
Correspondingly, the set of genera(.solutions is obtained as
Likewise, another such root
Correspondingly, one more set of general solutions
could be obtained.
Indeed, y becomes 0, for x=
