I insert the values of (u,v) until al my terms in the equation are in terms of u and v , correct? this is my final answer: [9 ln (4 Sq root of 3)]

The: 100 minutes 5. Consider the functions z = 9e* Iny, x = In(u cosv), and y = (u sinv). av (a) Express - and - as functions of u and v by using the chain rule and by expressing z directly in terms of u and v before differentiating. (b) Evaluate - and av at ( u, v) = (8, " )
