How to solve this equation?

Question

Python

I can't figure out how to specify proportionality and modulus in the code, I would be grateful if you could help me with the code

Answer 1

y = ((abs( pow(y1 - y2,  2*a) / pow(y1 + y2,  2*b) - asin(a) )) ** 1/4) * exp(-ctg(b) ** 2 )

something like this
