求 (1y)dx (x 1)dy=0的Can you help me out?If y = √((1x)/(1x)), then (1x 2)dy/dx y is equal to If y = 1/(az), then dz/dy = If y = 3at 2 /(1t 3) and x = 3at/(1t 3), then dy/dx is equal to If y = 5 x x 5, then dy/dx is equal to If y = a log x bx 2 x has its extremum value at x = 1 and x = 2, then (a, b) = If y = a x b 2x1, then d 2 y/dx
