Usually, computing work is done with respect to a straight force vector and a straight displacement vector, so what can we do with this curved path? This is a little unrealistic because it would imply that force continually gets stronger as you move away from the tornado's center, but we can just euphemistically say it's a "simplified model" and continue on our merry way. The definite integral of from to , denoted , is defined to be the signed area between and the axis, from to . This means that, Combining these pieces, we find that the flux through \(Q_{i,j}\) is approximated by, where \(\vF_{i,j} = \vF(s_i,t_j)\text{. , representing the velocity vector of a particle whose position is given by \textbf {r} (t) r(t) while t t increases at a constant rate.

Integration by parts formula: ?udv = uv?vdu? It calls Mathematica's Integrate function, which represents a huge amount of mathematical and computational research. To study the calculus of vector-valued functions, we follow a similar path to the one we took in studying real-valued functions. {2\sin t} \right|_0^{\frac{\pi }{2}},\left. In the case of antiderivatives, the entire procedure is repeated with each function's derivative, since antiderivatives are allowed to differ by a constant. When you multiply this by a tiny step in time, dt dt , it gives a tiny displacement vector, which I like to think of as a tiny step along the curve. In this section, we will look at some computational ideas to help us more efficiently compute the value of a flux integral. Wolfram|Alpha doesn't run without JavaScript.
