UNIVERSIDAD CARLOS III DE MADRID MATHEMATICS II EXERCISES (SOLUTIONS) CHAPTER 3: Partial derivatives and di erentiation Find @f @x, @f @y for the following functions: (a) f(x;y) = . Solutions to Exercises Exercise 2(a) The function z = (x2 + 3x)sin(y) can be written as z = uv, where u = (x2 + 3x) and v = sin(y). The partial derivatives of u and v with respect to the variable x are ∂u ∂x = 2x+3, ∂v ∂x = 0, while the partial derivatives with respect to y are ∂u ∂y = 0, ∂v ∂y = cos(y).

Here is a set of practice problems to accompany the Partial Derivatives section of the Partial Derivatives chapter of the notes for Paul Dawkins. MATH - Autumn Partial Differentiation: Extra Practice. In the lectures we went through Questions 1, 2 and 3. But I have plenty more questions to try!. UNIVERSIDAD CARLOS III DE MADRID MATHEMATICS II EXERCISES (SOLUTIONS) CHAPTER 3: Partial derivatives and di erentiation Find @f @x, @f @y for the following functions: (a) f(x;y) = . Let u1(x,t) denote the solution in Exercise 5 and u2(x,t) the solution in Exercise 7. It is straightforward to verify that u. u1 + u2 is the desired solution. Indeed, because of the linearity of derivatives, we have utt =(u1)tt +(u2)tt = c2(u1)xx + c2(u2)xx, because u1 and u2 are solutions of the wave equation.
