Calcolatore di derivate parziali

Calcola le derivate parziali passo dopo passo

Questo calcolatore online calcolerà la derivata parziale della funzione, mostrando i passaggi. È possibile specificare qualsiasi ordine di integrazione.

Enter a function:

Enter the order of integration:

Hint: type x^2,y to calculate `(partial^3 f)/(partial x^2 partial y)`, or enter x,y^2,x to find `(partial^4 f)/(partial x partial y^2 partial x)`.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Solution

Your input: find $$$\frac{\partial}{\partial x}\left(x y\right)$$$

Apply the constant multiple rule $$$\frac{\partial}{\partial x} \left(c \cdot f \right)=c \cdot \frac{\partial}{\partial x} \left(f \right)$$$ with $$$c=y$$$ and $$$f=x$$$:

$${\color{red}{\frac{\partial}{\partial x}\left(x y\right)}}={\color{red}{y \frac{\partial}{\partial x}\left(x\right)}}$$

Apply the power rule $$$\frac{\partial}{\partial x} \left(x^{n} \right)=n\cdot x^{-1+n}$$$ with $$$n=1$$$, in other words $$$\frac{\partial}{\partial x} \left(x \right)=1$$$:

$$y {\color{red}{\frac{\partial}{\partial x}\left(x\right)}}=y {\color{red}{1}}$$

Thus, $$$\frac{\partial}{\partial x}\left(x y\right)=y$$$

Answer: $$$\frac{\partial}{\partial x}\left(x y\right)=y$$$
