I worked a physics problem and the answer came down to solving these two equations and I am stuck.
2 equations and two unknowns.
sin(x) = (2/3)sin(y)
1 + cos(x) = (2/3) cos(y)
The Attempt at a Solution
I tried this and it went nowhere..
z =sin^-1[(2/3)sin(y)]- cos^-1[(2/3)cos(y) -1]
and set this to zero to solve for y.
This did not seem to work so there must be a better way.
