Document Summary
If f (x, y) = c, then dy dx. I"m just looking for the correct direction. : (10 points) let z = f (u, v) where u = x + y and v = x y. If f (x, y) = c, then dx dy. If f (x, y, z) = c, then. Fz: (12 points) three level curve plots are shown below. Write the correct formula below each plot. (b) sketch a gradient vector at the points a, b, and c. if the vector is 0, draw an x on the point. Make sure you clearly label regular derivatives with d"s and partials with "s. I measured and found that x = 2 and y = 1, but i think my measurement for x might be o by 0. 2 and my measurement for y might be o by 0. 1. / no (b) suppose fx and fy exist everywhere.
