+280 Provide an example of two complex numbers in the form c + di and e - fi, 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 and what quadrant it lies in.
(I'm having a hard time understanding how to actually do my own example, because I'm used to doing products in the form of:
r(cosθ+isinθ) x r(cosθ+isinθ).
So if someone could possibly just give me two complex numbers in the form of c + di and e - fi, then I could probably do the rest of the work. I'd appreciate if anyone could help me. Thank you loads!! xx)
