I need the solution

Consider the functions z= - e* In y, x=In(ucosv), and y=usinv. Express ou as a function of u and v by either using the Chain Rule or expressing z in terms of u and v explicitly and differentiate with respect to u. az Find each partial derivative needed to use the Chain Rule to find Bu: It will help to draw the dependence treee. Express Z directly in terms of u and v. z=[ | oz Using either method, aa = (Type an expression using u and v as the variables.)
