Help with complex numbers
Hello i'm getting ambiguity with the expression 1^i. 1 can be written as e^0 or e^(2pi*i) this leads to confusion because solving (e^0)^i, I obtain 1 and I simplify e^(2pi*i)^i and obtain e^(-2pi)... more

Help with finding out functions please.
Given that f(x) is a cubic function with zeros at −6 and −2i+4 , find an equation for f(x) given that f(−7)=−6. I keep getting (x^3+6x^2+8x+48)/(9.5) but it is wrong. Thanks in advance!
When dealing with complex numbers, does the i term get integrated as well? An example is an integration for e^4i
I am doing complex analysis. I am stuck on integrating sin^2(4x), from 0 to 2pi. I have to show the integration in exponential form.
