Computing line integrals

WebThere are two types of line integrals: scalar line integrals and vector line integrals. Scalar line integrals are integrals of a scalar function over a curve in a plane or in space. … WebThe Integral does calculate PI very accurately between those two bounds, it's just that the more iterations you do or the smaller dx is, the more accurate the value will approximate to PI. It is when the number of iterations is at infinity and dx approaches 0, that you will get the true value of PI.

WebFirst, there’s two types of line integrals: scalar line integrals and vector line integrals. Although these are related, we compute them in di erent ways. Also, there’s two theorems ying around, Green’s Theorem and the Fundamental Theorem of Line Integrals (as I’ve called it), which give various other ways of computing line integrals. WebIt is relatively easy to see why. Let C be the unit circle. The area under a surface over C is the same whether we traverse the circle in a clockwise or counterclockwise fashion, hence the line integral over a scalar field on C is the same irrespective of orientation. On the other hand, if we are computing work done by a force field, direction of travel definitely matters.
