Solve w=e^x+x\ln{y}+y\ln{x} - Socratic AI (ScanMath)

简化

w = e^{x} + x ln (y) + y ln (x)

通过将变量 y 视为常数并相对于 x 微分来求一阶偏导数

\frac{\partial w}{\partial x} = \frac{\partial}{\partial x} (e^{x} + x ln (y) + y ln (x))

使用微分规则 \frac{\partial}{\partial x} (f (x) \pm g (x)) = \frac{\partial}{\partial x} (f (x)) \pm \frac{\partial}{\partial x} (g (x))

\frac{\partial w}{\partial x} = \frac{\partial}{\partial x} (e^{x}) + \frac{\partial}{\partial x} (x ln (y)) + \frac{\partial}{\partial x} (y ln (x))

使用 \frac{\partial}{\partial x} e^{x} = e^{x} 求导数

\frac{\partial w}{\partial x} = e^{x} + \frac{\partial}{\partial x} (x ln (y)) + \frac{\partial}{\partial x} (y ln (x))
