To do this set the two elements of in the utility function equal to each other so there is no extra X or Y being consumed that gives no extra utility. The next step is to pretend that $f(x)$ doesn't change over each subinterval. For most points on most surfaces, different sections will have different curvatures; the maximum and minimum values of these are called the principal curvatures. By looking at the graph, we can see that it intersects the y-axis We get "3 = 3", a true statement, so this point satisfies the equation of the line. The simplest way to do this is by linear interpolation, which assumes that the line segments between points can be approximated by a straight line. We will also see how the parameterization of a surface can be used to find a normal vector for the surface (which will be very useful in a couple of sections) and how the parameterization can be used to find the surface area of a surface. We find the intersection slightly differently. (tcost)2 +(tsint)2 = t2 cos2 t+t2 sin2 t= t2(cos2 t+sin2 t) = t2 It lies on z2 = x2 +y2. Relative viscosity is self-explanatory.
