Woops, my bad, that should be lowercase L.

e/ L is after J in the alphabet. Right. I would need to solve for triangle DRF somehow. I'll post a different solution in a bit

When I get home I'll see if i can get a neater final solution. (though I only just went through trig (starting BC) so I don't know many tricks)

2E/ fixed that error. working on a latex solution

3E/ i feel like i should be doing something with all of those cos(arcsin() - arcsin())

Code:
\frac{2 * \sqrt{z^2 + a^2}*cos(arcsin(a/b))}{cos(arcsin(a/\sqrt{a^2+(z-y)^2})-arcsin(\frac{bsinc}{\sqrt{a^2+(z-y)^2}})-arcsin(\frac{a}{b})-arcsin(\frac{bsin(arcsin(\frac{bsinc}{\sqrt{a^2+(z-y)^2}})-arcsin(\frac{a}{b}))}{\sqrt{2*b*\sqrt{a^2+(z-y)^2}*cos(arcsin(\frac{bsinc}{\sqrt{a^2+(z-y)^2}})-arcsin(\frac{a}{b}))}))}}
