De Moivre's theorem gives a formula for computing powers of complex numbers. We first gain some intuition for de Moivre's theorem by considering what happens when we multiply a complex number by itself. Recall that using the polar form, any complex number

The well-known shoelace algorithm (shoelace formula) is used to calculate the area related problems in polygons. The algorithm is called so, since it looks like a  

Then, A 3 = 1 2 2 a 1 b 1 a b 2 a 3 b 3 a 1 b 1 = where jajis called the The shoelace algorithm Green’s theorem can also be used to derive a simple (yet powerful!) algorithm (often called the “shoelace” algorithm) for computing areas. Here’s the idea: Suppose you have a two-dimensional polygon, where the vertices are identified by their -coordinates: The shoelace formula, or shoelace algorithm, is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by ordered pairs in the plane. The user cross-multiplies corresponding coordinates to find the area encompassing the polygon, and subtracts it from the surrounding polygon to find the area of the polygon within. With the Shoelace formula, the calculation would be as follows: U nderstanding how one representation con-nects to another and how the essential ideas in that relationship are generalized can result in a mathematical theorem or a formula.

Here’s the idea: Suppose you have a two-dimensional polygon, where the vertices are identified by their -coordinates: The shoelace formula found here or here tells you how to calculate the area of any polygon given its coordinates. The second link I mentioned gives a proof of it, but it is a bit beyond my level of comprehension. Could anyone try to simplify the proof (or provide their own) to a level up to and including single variable calculus? Method 4: Shoelace Theorem Also known as \Shoelace Formula," or \Gauss’ Area Formula" Shoelace Theorem (for a Triangle) Suppose a triangle has the following coordinates: (a 1;b 1), (a 2;b 2), (a 3;b 3) where a 1;a 2;a 3;b 1;b 2; and b 3 can be any positive number. Then, A 3 = 1 2 2 a 1 b 1 a b 2 a 3 b 3 a 1 b 1 = where jajis called the The shoelace algorithm Green’s theorem can also be used to derive a simple (yet powerful!) algorithm (often called the “shoelace” algorithm) for computing areas.

The shoelace formula or shoelace algorithm is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. The method consists of cross-multiplying corresponding coordinates of the different vertices of a polygon to find its area.

The method consists of cross-multiplying corresponding coordinates of the … 2019-10-7 · The Shoelace Algorithm to find areas of polygons This is a nice algorithm, formally known as Gauss’s Area formula, which allows you to work out the area of any polygon as long as you know the Cartesian coordinates of the vertices. 2020-9-13 · I am learning about complex numbers and I have found this theorem similar to the shoelace theorem for Cartesian Coordinates But im not sure how to calculate this (?). I can't find any explanation 2021-2-21 · The fact that the shoelace formula is a consequence of Green’s theorem means that there should be a way to take it to higher dimensions. Green’s theorem readily generalizes to Stoke’s Theorem in arbitrary spaces, which says that the integral of a function (or differential form) over a closed surface can be equated to the integral of its 2020-3-1 · 当知道三角形三个顶点的坐标时，我们也可以用（7）Shoelace Theorem 关于定理的证明详见《任意多边形面积计算公式》 如果再特殊一点，三角形的顶点都在格点上，我们还可以用（8）Pick's Theorem 总结： 这里我们介绍了很多种三角形面积的计算公式 2020-9-29 · The shoelace formula, or shoelace algorithm, is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by ordered pairs in the plane.

The explanation of the planimeter through Green's theorem seems have been given first by G. Ascoli in 1947 . It is further discussed in classroom notes [4,2]. A web source is the page of Paul Kunkel , which contains an other explanation of the planimeter. 2009-03-09 · Let’s see how the Shoelace Theorem got its name. First write down the coordinates of the vertices in a vertical line.

Now, you subtract the second value from the first one to get 0-12 which is negative 12. You take the absolute value of the number which is 12 and divide by 2 to get the area of the triangle. 为什么叫Shoelace Theorem，因为这个公式的运算很像鞋带，我们来看看三个顶点时的公式计算， ，就如下图所示：.
