Provide an example of two complex numbers in the form c + di and , where c, d, e, and f are positive real numbers such that their product lies in the other possible quadrant. Support your example by determining its product.
Two complex numbers: c+di and e+fi.
The product is (c+di)(e+fi) = ce+cfi+dei+dfi^2 = (ce-df)+i(cf+de)
Can you go from here?
You are very welcome!
