Ran in:
syms x
part1 = int(sin(x)*exp(x)*exp(-1i*x), x, -10, 0)
part1 = 
part2 = int(sin(x)*exp(-x)*exp(-1i*x), x, 0, 10)
part2 = 
overall1 = simplify(part1 + part2)
overall1 = 
or...
syms x
overall2 = simplify(int(sin(x)*exp(-abs(x))*exp(-1i*x), x, -10, 10))
overall2 = 
isAlways(overall1 == overall2)
ans = logical
