Hmm, this sequence of numbers looks familiar. Fibonacci, is that you? 1 + (-1) + 3*i*(*i*^{4}) + 8*i*(*i*^{4})^{3} + 21*i*^{2}(*i*^{4})^{8} When you have an exponent of *i*, check to see if it 4 or less. If so, simplify. If not, find as many powers of 4 as you can, because each *i*^{4} equals 1, which will multiply out without consequence. 0 + 3*i* + 8*i* + 21(-1) -21 + 11*i* Remember to put the real number portion first and the imaginary part second. |
