WebQuestion: Using the identities cos z= e^iz + e^-iz/2, sinz = e^iz - e^-iz/2i, established from comparison of power series, show that sin(x + iy)=sin x cosh y + i cos x sinh y, cos(x+iy) …

9 De nite integrals using the residue theorem

WebQuestion: Using the formula sin z = e iz − e −iz 2i and formulas for e z, prove the following: Points πk, where k is an integer (so k = 0, ±1, ±2, . . .) are the only points in the complex plane where the function sin z is equal to 0. Web2 Answers. e − y cos x = 1, e − y sin x = 0. and therefore k has to be even, and y = 0. Hence z = 2 k π, where k ∈ Z. Use Euler's formula: e i z = cos z + i sin z. Note that for 1 = cos z … movie theaters near dennis ma
