For what r and θ does r cos θ + i sin θ 8i

Webx = r cos ( t) = a sin ( t) cos ( t) + b cos 2 ( t) = a 2 sin ( 2 t) + b 2 ( 1 + cos ( 2 t)) y = r sin ( t) = a sin 2 ( t) + b sin ( t) cos ( t) = a 2 ( 1 − cos ( 2 t)) + b 2 sin ( 2 t) Hint 2: Therefore, if we set ( b, a) = a 2 + b 2 ( cos ( θ), sin ( θ)), we get ( x, y) = 1 2 ( b, a) + 1 2 a 2 + b 2 ( cos ( 2 t − θ), sin ( 2 t − θ)) WebStep 3 For I = 1 and m = ± 1, the spherical harmonics Y 1 1 and Y 1 − 1 are: Y 1 1 = A 1 1 sin θ e i φ Y 1 − 1 = A 1 − 1 sin θ e − i φ Using the trigonometric identities sin θ cos φ = r x , sin θ sin φ = r y , and cos θ = r z , we can express these spherical harmonics in terms of Cartesian coordinates: For I = 1 and m = ± 1 ...
