Chirag - that line of code plot[x0i,x1i],[y0i,y1i]is using the square brackets to concatenate two elements together to create two 1x2 arrays. These arrays, or coordinates, are then used to plot a line with an origin of x0i,y0i and an end point of x1i,y1i. Put a break point at this line and run the above code. When the debugger pauses at this line, look at the inputs coordinates and see how they are used to draw the line on the figure for each iteration of the loop. In this very article, we are going to discuss various forms of the equation of a line. A coordinate plane consists of an infinite number of points. If we consider a point Px,y in a 2d plane and a line named it as N. Then what we will determine is that the point we consider lies on the line L or it lies above or below of the line. That’s when straight-line comes into this scenario. Here we will include the important topic related to the equation of a line in different forms. Forms of the Equation of the LineBased on the parameters known for the straight line, there are 5 forms of the equation of a line that is used to determine and represent a line's equationPoint Slope Form –This form requires a point on the line and the slope of the line. The referred point on the line is x1,y1 and the slope of the line is m. The point is a numeric value and represents the x coordinate and the y coordinate of the point and the slope of the line m is the inclination of a line with the positive m can have a positive, negative, or zero slope. Hence, the equation of a line is as follows y - y11 = m x - x11Two Point Form –This form is a further explanation of the point-sloon of a line passing through the two points - x11, y11, and x22, y22 is in this wayy−y1=y2−y1x2−x1x−x1y−y1=y2−y1x2−x1x−x1Slope Intercept Form –The slope-intercept form of the line is y = mx + c. And here, 'm' is the slope of the line and 'c' is the y-intercept of a line. This line cuts the y-axis at the point 0, c, where c is the distance of this point on the y-axis from the slope-intercept form is an important form and has great applications in the different topics of = mx + cIntercept Form –The equation of a line in this form is formed with the x-intercept a and the y-intercept b. The line cuts the x-axis at a point a, 0, and the y-axis at a point0, b, and a, b are the respective distances of these points from the origin. While these two points can be substituted in a two-point form and simplified to get this intercept form of the equation of a intercept form of the equation of the line explains the distance at which the line cuts the x-axis and the y-axis from the Form –The normal form is based on the line perpendicular to the given line, which passes through the origin, is known as the the parameters of length of the normal is 'p' and the angle made by this normal is 'θ' with the positive x-axis is useful to form the equation of a line. The normal form of the equation of the line is in this wayxcosθ + ysinθ = PDifferent Forms of the Equation of a Straight LineA. Equation of Line Parallel to the y-axisEquation of a straight line which is parallel to the y-axis at a distance of a’ then the equation of y-axis will be x=a here a’ is a coordinate in the plane.Consider this example Equation of line parallel to y-axis for coordinate 7,8 is x=8 B. Equation of Line Parallel to the x-axisEquation of a straight line if the straight line is parallel to the x-axis the equation will be y=a where a’ is an arbitrary understand one can consider this example, consider this a point 9,10 Equation of line parallel to the x-axis is x=9 C. Point- slope Form of an EquationLet a line passing through a particular point QX1, Y1 and PX, Y be any point present in the mentioned slope of a line= Y - Y1/X – X2And by the definition m is the slope,Hence, m = Y - Y1/X – X2On comparing Y – Y1 = mX – X1 is the required point-slope form equation of a line D. Equation of the Line in Two-point FormConsider an arbitrary constant Px,y present in the line L and the Line L passes through two points Ax1,y1 and Bx2,y2. We consider m’ as the slope of the line y2-y1 / x2- x1Then the equation of the line isy2-y1 = mx2-x1Substituting the value of m we gety-y1={ y2- y1/ x2-x1}x-x1Equation of the required line in two point form is y - y1= y2- y1/ x2 - x1x -x1.E. Equation of a Line in Intercept FormLet AB line cuts intercept on the x-axis at a, 0 and on the y-axis at 0, bFrom two-point form y = -b/a x – a y = b/a a – x x/ a + y/b = 1 is the required equation of line in intercept formExampleConsider finding the equation of a line which has made an intercept of 4 in x axis and has made a cut of y-axis in the graphSolutionSo, b = -3 and a = 4 x/4 + y/-3 = 1 3x – 4y = 12 hence the required equation of a line in intercept formSlope-intercepts Form of a LineConsider a line L whose slope be m which cuts an intercept on the y-axis at the distance of a’. hence the point is 0, aHence, the required equation is y – a = mx – 0 y = mx + a which is the required equation of a the equation of a line which has a slope of -1 and has an intercept of 4 units in the positive section of the m = -1 and a = -4Substituting this value in y = mx + a we get y = -x – 4 x + y + 4 = 0Solved ExamplesExampleDetermine the equation of a line which passes through the point -4, -3 and it is parallel to the m = 0, X1 = -4, Y1 = the above equation Y + 3 = 0X + 4 Y = -3 is the required equationExampleFind the equation of the line joining by the points 4,-2 and -1,3.Solution here the two given points are X1,Y1 = -1,3 and X2,Y2= 4,-2Equation of line in two point form is y – 3 = { 3 – - 2/ -1 – 4 } x+1 - x – 1 = y – 3 x + y – 2 = 0. capacitor, kondensatoren, kondensator image by Sascha Wilsrecht from Os capacitores são componentes eletrônicos passivos usados em muitos circuitos para realizar uma variedade ampla de funções, desde osciladores a fornecedores de energia. Um uso específico de capacitores é para fornecer energia a filtros de linha em muitos dispositivos e aparelhos eletrônicos. Os capacitores usados nessas aplicações são classificados como Classe X ou Classe Y, e então divididos pela sua voltagem testada, como X1 e Y2. Essas designações de classe se referem à segurança do capacitor e sua como filtros de linha "Ruído" elétrico é um tipo de interferência sintonizada pelas linhas domésticas. A eletricidade que vem para sua casa não é sempre pura e limpa. Ela pode ter picos de tensão ocasionais, que são tempos momentâneos em que ela oscila. Isso é comum quando há muita corrente fluindo simultaneamente, o que ocorre, por exemplo, quando vários aparelhos de ar condicionado e um refrigerador funcionam ao mesmo tempo. A iluminação por perto pode induzir picos de voltagem, assim como um carro atingindo um telefone ou um esquilo destruindo terminais em um transformador elétrico. Os contatos elétricos em motores podem enviar variações de voltagem falsas de volta à instalação elétrica. Outros tipos de impurezas consistem em frequências de rádio ou interferência de radiofrequência RF, que podem ser causadas por transmissões de meios de comunicação. Mesmo um interruptor de luz irá produzir um ruído através da fiação de sua casa. Capacitores de filtro de linha são usados para reduzir ruídos elétricos e de RF. Capacitores de Classe X Para "tirar" um pouco do ruído de rádios, televisões e outros aparelhos eletrônicos, geralmente se utiliza um capacitor conectado a duas linhas AC, dentro do dispositivo. Os capacitores que realizam essa tarefa de filtrar a linha são classificados como do tipo "X". Se um desses tipos falhar, uma de duas coisas pode acontecer. Se o capacitor "abrir", então será como se ele não estivesse lá. Isso não apresenta nenhum perigo ao usuário do dispositivo, mas pode resultar em um desempenho ruim. Se ocorrer um curto-circuito, isso irá derrubar o fusível no dispositivo ou o disjuntor da sua casa. Novamente, isso não causa riscos ao usuário. Capacitores de Classe Y Um filtro de linha coloca um capacitor entre uma das linhas AC e o chassi do dispositivo. Essa configuração usa o capacitor de Classe Y. Muitos aparelhos de hoje possuem ligação terra que conecta o chassi e o revestimento de metal à "terra" elétrica ou neutra. Tais aparelhos têm três pinos de tomada. Se sua casa tem fiação apropriada, o pino de tomada faz a ligação terra. Não haverá nenhum perigo se um capacitor da classe Y "abrir", mas uma falha irá causar um choque elétrico ou até mesmo a morte da pessoa se o aparelho não estiver fazendo a ligação apropriadamente. O chassi ou revestimento devem ficar quentes, isto é, estariam no potencial elétrico na tomada. Taxas de capacitores de segurança Nos Estados Unidos, onde a voltagem doméstica padrão é de 120 volts, os capacitores de segurança têm uma taxa de 250 volts, mais do que o dobro da voltagem operacional esperada. Porém, eles podem falhar, seja atingidos por uma oscilação de alta voltagem ou devido ao tempo, já que ressecam e ficam deteriorados. Classificação X1, X2, Y1 e Y2 Os capacitores classe X e Y também recebem um número que representa sua taxa de estímulo. Os mais comuns são o X1 testado a 4000 volts, o X2 2500 volts, o Y1 8000 volts e o Y2 5000 volts.
