For the functions w = xy + yz + xz, x=u +21, y=u-2v, and zuv, express dw du dw and ar using the chain rule and by expressing w directly in terms of u and v before differentiating. Then evaluate dw du dw and ov at the point (u, v) = اله | العيا dw dw Express and du ov as functions of u and v dw du dw av Evaluate dw and du ow ar at Nim dw du (64) (Type an integer or a simplified fraction) dw ov (Type an integer or a simplified fraction)
