GRE Subject Test: Math : Functions of More Than Two Variables

Example Questions

Example Question #131 : Calculus

Solve for :       Explanation:

To solve for the partial derivative, let all other variables be constants besides the variable that is derived with respect to.

In , the terms are constants.

Derive as accordingly by the differentiation rules. Example Question #1 : Functions Of More Than Two Variables

Suppose the function .  Solve for .      Explanation:

Identify all the constants in function .

Since we are solving for the partial differentiation of variable , all the other variables are constants.  Solve each term by differentiation rules. Example Question #1 : Functions Of More Than Two Variables
