Please help solve for frequency & angle in dispersion equation

[NiToNi]

OK I'm about to grow (more) gray hairs....

Could some friendly soul smarter than myself kindly help me solve for both f and theta respectively in the following equation, please:

x = sin[ (pi*f*W)/c * sin(theta) ] / [ (pi*f*W)/c * sin(theta) ]

Getting stuck at "arcsin of arcsin" sort of thing....

Many thanks in advance :grin:

Please reply showing what you've done so far so we can see what's going on (you may be almost there!).

Thank you!
