Operators such as divergence, gradient and curl can be used to analyze the behavior of scalar- and vector-valued multivariate functions. is called a vector-valued function in 3D space, where f (t), g (t), h (t) are the component functions depending on the parameter t. We can likewise define a vector-valued function in 2D space (in plane): The vector-valued function \(\mathbf{R}\left( t \right)\) is called an antiderivative of the vector-valued function \(\mathbf{r}\left( t \right)\) whenever, In component form, if \(\mathbf{R}\left( t \right) = \left\langle {F\left( t \right),G\left( t \right),H\left( t \right)} \right\rangle \) and \(\mathbf{r}\left( t \right) = \left\langle {f\left( t \right),g\left( t \right),h\left( t \right)} \right\rangle,\) then. Since the derivative of a constant is 0, indefinite integrals are defined only up to an arbitrary constant. The indefinite integral of the function is the set of all antiderivatives of a function. If the two vectors are parallel than the cross product is equal zero. In the case of antiderivatives, the entire procedure is repeated with each function's derivative, since antiderivatives are allowed to differ by a constant. For those with a technical background, the following section explains how the Integral Calculator works. ?\int r(t)\ dt=\bold i\int r(t)_1\ dt+\bold j\int r(t)_2\ dt+\bold k\int r(t)_3\ dt??? A vector function is when it maps every scalar value (more than 1) to a point (whose coordinates are given by a vector in standard position, but really this is just an ordered pair). Use parentheses, if necessary, e.g. "a/(b+c)". Since C is a counterclockwise oriented boundary of D, the area is just the line integral of the vector field F ( x, y) = 1 2 ( y, x) around the curve C parametrized by c ( t). {du = \frac{1}{t}dt}\\ To derive a formula for this work, we use the formula for the line integral of a scalar-valued function f in terms of the parameterization c ( t), C f d s = a b f ( c ( t)) c ( t) d t.
