WebJan 16, 2024 · 4.1: Line Integrals. In single-variable calculus you learned how to integrate a real-valued function f(x) over an interval [a, b] in R1. This integral (usually called a Riemann integral) can be thought of as an integral over a path in R1, since an interval (or collection of intervals) is really the only kind of “path” in R1. WebWhat Sal is saying at the end is that when you integrate "over the surface" which is the parameterized r (s,t) with the scalar function f (x,y,z) as part of the integrand, then you get a new value (and that can be useful in certain physics problems). f (x,y,z) is not a surface itself - we are just "sampling" or "reading out" it's value at each ... spray for blisters on feet
