Simplify i^{4}?
Simplify i4?
We know that i = -11/2
Therefore i2=-1
As i4=i2xi2
Then i4=-1x-1=1

The infinite series C and S are defined C = a*cos(x) + a^2*cos(2x) + a^3*cos(3x) + ..., and S = a*sin(x) + a^2*sin(2x) + a^3*sin(3x) + ... where a is a real number and |a| < 1. By considering C+iS, show that S = a*sin(x)/(1 - 2a*cos(x) + a^2), and find C.
