we observe that complex exponentials in trig functions are not bounded prove using cos(iy)=cosh(y)=\frac{e^{y}+e^{-y}}{2} where y\in R and it becomes arbitrarily large as y\rightarrow\pm\infty, hence unbounded will later prove the only bounded entire functions are constant function...
This set of points is your basis set for the Discrete Fourier Transform (DFT) and are called the Roots of Unity.Similar considerations occur taking inverse trig functions. acos(cos(theta)) may not equal theta cos(acos(x)) always equals xIt's important to know your tools. Sometimes ...
