Use the Chain Rule to find $\frac{\partial z}{\partial s}$ and $\frac{\partial z}{\partial t}$. $z = \sin(\theta) \cos(\phi)$, $\theta = st^2$, $\phi = s^2t$ $\frac{\partial z}{\partial s} = $ $\frac{\partial z}{\partial t} = \cos \theta \cos \phi 9t^2s^2 - \sin \theta \sin \phi s^3$
Texts: Assignment 1: Problem 4 (1 point) Complex numbers z1 and z2 are given by z1 = -5 + j - 7 z2 = -7 + j - 5 (a) Express z1 and z2 in polar form. (b) Find |z1| and |z2|. (c) Determine the product z1 * z2 in polar form. (d) Determine the ratio z1/z2 in polar form. (e) Determine z1^4 in polar form (please input the phase part within the range of -179° < θ < 180°). Answers: (a) z1 = r1 * exp(jθ1) and z2 = r2 * exp(jθ2) (b) |z1| = r1 and |z2| = r2 (c) z1 * z2 = r1 * r2 * exp(j(θ1 + θ2)) (d) z1/z2 = (r1/r2) * exp(j(θ1 - θ2)) (e) z1^4 = r1^4 * exp(j(4θ1))
