Question

# If then

Hint:

### We are given a function. It is function of two variables x and y. We should to find the value of f_{xy}.

## The correct answer is:

### The given function is f(x,y) = sin(e^{ax }+ e^{by})

We have to find the value of f_{xy}

It means we have to find the value of

We will first take partial derivative w.r.t to one of the variable. Then we take the partial derivative of that value w.r.t the remaining variable.

Taking the partial derivative w.r.t x

We will take the derivative of this value w.r.t y

This is the required answer.

We have used rules of indices and different formulae of differentiation to solve the question. When we find the derivative w.r.t to some variable we take another variable as consta.
