    Section 2.4
    Question 56

    (2i)/(2 + i) + (5)/(2 - i)

    (2i)/(2 + i) + (5)/(2 - i)

    Let (2i)/(2 + i) = 0.4 + 0.8i.

    Let (5)/(2 - i) = i + 2

    I now get 0.4 + 0.8i + i + 2.

    When adding, I get 2.4 + 1.8i.

    You say?

    Complex numbers at this level are not too hard. Is there such a thing as calculus of complex numbers?
