解:由第1.种情况的链式法则得 dzdt=∂f∂xdxdt+∂f∂ydydt =(2xy+3y4)⋅2cos2t+(x2+12xy3)(−sint) . 将 x|t=0=0 和y|t=0=0 代入,得 dzdt|t=0=(0+3)⋅2+(0+0)⋅0=6 .2. 若z=e^x\sin y ,其中 x=st^2, y=s^2t ,求 \frac{\partial z}{\partia...
Use the chain rule to find dzdt, where z=x2y+xy2, x=−5−t7, y=−2+t5. Chain Rule: You have to find the dzdt. You will use chain rule to find the desired result. First you will find the derivative of x,y,z with respect to t and then s...
Use the Chain Rule to finddzdtwhen: z2=x2+y2,x=t2+1andy=t−1. Chain Rule: We must differentiate implicitly with respect tot Steps: 1. Since,z2is a function of two variablesxandy, we differentiate it partially and compute∂z∂xand∂z∂y ...
Let’s take a look at an example that shows how the chain rule works. Example: The number of footballs a sporting goods store sells over time is x(t) t4+ 1; y(t) = 3t2+ 6 describes the price of footballs over time. Let z(t) = xy represent the revenue the store earns from ...
def calc_MI(x, y, bins): c_xy = np.histogram2d(x, y, bins)[0] mi = mutual_info_score(None, None, contingency=c_xy) return mi But I'm not sure how to move forward, thanks in advance. If you want to computeI(A;BC)you do not necessarily have to use the conditional mutual...
Find∂f∂yfor the functionf(x,y)=4x4y2+9xy. The derivative is with respect to y. Treating x as a constant the derivative is : Using the power rule to take a partial derivative with respect to y. The next section looks at how to apply the chain rule to a multivariable function...
