Just to add a little fillip to this original query of mine, I'll make a
the following challenge/good faith offer:
If any regular posters to either of these groups can identify any
published optics or e-m theory text in which Snell's Law is written as
n1 Csc[ theta2 ] = n2 Csc[ theta1 ]
n1 Sin[ theta1 ] = n2 Sin[ theta2 ]
and Brewster's angle is written as
Cot[ thetaB ] = n1 / n2
Tan[thetaB] = n2/n1
(or any algebraically equivalent formulations using "cosecant" or
cotangent"), I'll write a $20 check to any (one!) U.S. tax-deductible
charitable organization selected by the first such responder . (Time of
email receipt in my MacBook Eudora IN box determines "first").
