Find all real numbers x such that

What does it mean for sin(x) = sin(y)? I.e. find a relationship between x and y. Then simply add on the addition restraint that x = pi*y/180.

This reminds me of the minute and hour hand passing each other on a clock.
Like for 2 pi, you need to go 2pi + 6.29 degrees or so.
What am I saying? Like 6.35 degrees and 6.35 radians maybe??
How about 12.7 radians and degrees?? Just guessing here.

I just used google as a calculator and came up with
this after about ten iterations.
sin(12.78959) = 0.221370277
sin(12.78959 degrees) = 0.22137132
The first one is in radians.
