SUMMARY
The discussion centers on proving DeMoivre's Theorem for complex numbers, specifically using the complex number (1+i). The participants agree that expressing (1+i) in trigonometric form is essential, resulting in the expression 2^(n/2)*(cos(45*n)+i*sin(45*n)). This formulation directly applies DeMoivre's Theorem, which states that for any complex number in trigonometric form, raising it to the nth power involves multiplying the modulus by n and adding n times the angle to the argument.
