Now you have not only a means of condensing down any triangle into a singular equation, but also the method for putting together any polygon into such an equation, as well as any random collection of line segments, rays, or any other items for which you have a standard equation, so hopefully this was a useful answer, despite all the voodoo ...

2013年9月24日 · Let's just take the equation x=y on a plane, and we want to cut that line to make it a line segment from (-1,-1) to (2,2). First we remove everything from x=-1 and below by multiplying any side of the equation by √(x+1)/√(x+1). This just multiplies the equation by one and also makes the equation indeterminate whenever x < -1.

2016年5月1日 · For part a, I can say that the amplitude is 2 because it covers 1 to -3. I am confused why d is not in this equation as the graph has been vertically shifted -1 units or is it that c is -1 in this graph? For B or the period, a period of 1 is $360^{\circ}$ but this graph only goes to 120 so ${360\over120} = 3$,so b is 3.

I'm doing a calculus project where we have to make a model of some graph rotated about the y axis. I am doing a fish bowl and I have most of it understood and ready. The only thing I'm not sure of is what the equation of the semicircle is if its center is at (0,1.5). I added a picture to help illustrate it. Thank you for your help. Image of ...

2017年11月7日 · In order to arouse interest of my high school students to plot graphs I want to plot interesting funny graphs such as the one of the batman equation. I'm looking something simpler, maybe in a form ...

This equation is actually just the polar equation for the line through the point $(1,0)$ and $(\cos(2\pi/n

2011年10月2日 · If the equations of the diagonals of the rectangle are Ax + By + C = 0 and Dx + Ey + F = 0 then an equation for the rectangle is: M|Ax + By + C| + N|Dx + Ey + F| = 1. M and N can be found by substituting the coordinates of two adjacent vertices of the rectangle. In fact, this equation can be used to describe any parallelogram.

I know there are many sites where we can input the equation and get the curve of the function (examples here, here and here). What I want is the inverse: I have an idea of how I want the curve to be, and want to get to the equation from there.

2015年9月10日 · $\begingroup$ But in another sense, it is completely incorrect that any "graph" corresponds to some equation(s) or other finite string of symbols. Take for exaple all "graphs" consisting of a single horizontal line only.
