Surface Area of a Parameterized Surface

Multivariable calculus core

Find the surface area of the surface with parameterization \( \mathbf{r}(u,v) = \langle u+v, u^2, 2v \rangle \), \( 0 \le u \le 3 \), \( 0 \le v \le 2 \).

What you need first

Partial derivatives
Cross product of vectors
Double integrals
Integration of functions involving square roots of quadratics

What this problem tests

Tests the ability to compute partial derivatives of a vector function, find the cross product, set up a double integral for surface area, and evaluate it using advanced integration techniques.

This problem is typical in a Multivariable Calculus (Calculus III) course when introducing surface integrals and parameterized surfaces.
