WebSolution Given, $$z=\dfrac{3}{2+i\sin\theta+\cos\theta}$$ $$\therefore \cos\theta+i\sin\theta=\dfrac{3}{z}-2=\dfrac{3-2z}{z}$$ Taking the modulus, $$\left z\right ... WebLet z = cos θ + i sin θ, then the value of ∑ m = 1 15 I m ( z 2 m - 1) is Solution Step 1: Find the value of ∑ m = 1 15 I m ( z 2 m - 1) Given that, z = cos θ + i sin θ We can write the above equation as z = cos θ + i sin θ = e i θ We also have, ∑ m = 1 15 I m ( z 2 m - 1) = ∑ m = 1 15 I m e i θ 2 m - 1 = ∑ m = 1 15 I m e i 2 m - 1 θ doctrine of inordinate delay

Since the cosine is the x -coordinate of the points on the unit circle, you see that the two points have the same cosine, and opposite sine. In fact, the cosine is an even function, which means exactly that cos(x) = cos( − x), while the sine is odd, which means that sin(x ... doctrine of informed consent case
