Homework Statement
They ask me to solve the characteristic equation of a fiber optics glass. The equations I need to solve (separately) are:
Homework Equations
solve(2000000*Pi*sin(x)-2*arctan(.6666666667*(2.25*cos(x)^2-2.1904)^.5/sin(x)) = Pi, x):
solve(2000000*Pi*sin(x)-2*arctan(.6666666667*(2.25*cos(x)^2-2.1904)^.5/sin(x)) = 0, x)
That's how I tried to solve them in MAPLE.
The Attempt at a Solution
Maple is not giving me answers, I used my TI and it gave me some results but they were extremely similar and I don't think they are the real ones. How can I solve for the propagation angle x?
