How to evaluate a line integral with ds (scalar line integral, calculus 3) @bprpcalcbasics

Uploaded February 2026 | Updated September 2026, 2 weeks ago

Here's an example of a scalar line integral, taken from the multivariable calculus textbook by James Stewart. We will integrate y*sin(z) with respect to the arc length, over the curve r=cost(t)i+sin(t)j+tk
