If you get $536.49 for that check, take the cash and run. It was only written out for $0.002
The second term wasn't e^(2*
pie[sic]) it was e^(i*pi) which is equal to -1 from Euler's identity (one of the coolest equations ever):
e^(i*pi) + 1 =0, so e^(i*pi) = -1
The infinite series in the third term works out to 1 as expressed
So the check is for $(0.002 -1+1) = $0.002.
