## Question:

Consider the following multivariate function:

{eq}Y = 6X_{1} X_{2}^{\frac{1}{2}} {/eq}

i) Find the partial derivative of Y with respect to {eq}X_{1} {/eq}

ii) Find the partial derivative of Y with respect to {eq}X_{2} {/eq}

## Partial Derivatives:

The partial derivative of a function of several variables is the derivative of the respective variable holding all other variables as constant. The regular rules of differential apply when taking partial derivatives. Partial derivatives are often used in optimization problems where functions depend on several variables.
