3) You may have noticed that the series representations for ex, sinx, and cos x look very similar. One of the most important results in complex analysis is the identity eix = cos x + i sin x where i = √√-1 is the imaginary unit. Prove this identity using Maclaurin series. (Fun fact: When you plug in to this identity, you get Euler's formula: ei + 1 = 0, a formula that includes all of the most important numbers in math!)
