Find the union of the following sets, namely ${-5.469, 1, -7, 4, \frac{15}{e}, 7, \frac{9}{\sqrt{2}}} \cup {-\frac{11}{\sqrt{2}}, 9, 4, \frac{15}{e}, -8, -3.109, -7}$.

import math

fst = set((-5.469, 1, -7, 4, (15/math.e), 7, (9/(math.sqrt(2))),))
snd = set((-(11/(math.sqrt(2))), 9, 4, (15/math.e), -8, -3.109, -7,))
print(fst.union(snd))
