The next activity asks you to carefully go through the process of calculating the flux of some vector fields through a cylindrical surface. The formula for calculating the length of a curve is given as: L = a b 1 + ( d y d x) 2 d x. Vector-valued integrals obey the same linearity rules as scalar-valued integrals. This includes integration by substitution, integration by parts, trigonometric substitution and integration by partial fractions. The \(3\) scalar constants \({C_1},{C_2},{C_3}\) produce one vector constant, so the most general antiderivative of \(\mathbf{r}\left( t \right)\) has the form, where \(\mathbf{C} = \left\langle {{C_1},{C_2},{C_3}} \right\rangle .\), If \(\mathbf{R}\left( t \right)\) is an antiderivative of \(\mathbf{r}\left( t \right),\) the indefinite integral of \(\mathbf{r}\left( t \right)\) is.
