Final 21C Winter 2002 1. (9) Compute f y where f (x,y) = xy e 2 x sin(!y) 3 . 2. a. (8) Suppose you know at some point that ! f ! x = 2, ! f ! y = -3, ! x ! s = -5, ! x ! t = 5, ! y ! s = 4, ! y ! t = -2. What is the value of ! f ! t ? b. (8) Suppose in addition that you know ! s ! u = 2, ! t ! u = 3, what is the value of ! f ! u ? 3.
