1. from math import sin, e, pi, pow
   
2. 
   
3. def A(x, y):
   
4.     return sin(pow(((2 * pi * x) / 3), 2)) * sin(pow(((2 * pi * y) / 3), 2)) * pow(e, (x + y) / (5 * pi))
   
5. 
   
6. def B(x, y):
   
7.     return -sin(pow(((2 * pi * x) / 3), 2)) * sin(pow(((2 * pi * y) / 3), 2)) * pow(e, (x + y) / (5 * pi))
   
8. 
   
9. z = lambda x, y: A(x, y) if (-3 < x < -2.5 and -3 < y < -2.5) or (2.5 < x < 3 and 2.5 < y < 3) else B(x, y)
