But let's not reveal it just yet! How about we see how to find the endpoint ourselves using the endpoint formula? Once we input all this data into the endpoint calculator, it will spit out the answer. Again, the starting point was when we had no one, while right now, after four months, we're at 54,000. Since our starting point was month zero, and we're currently 4 months in, we have (and can input into the endpoint calculator): For us, the x's will denote the number of months in we are, and the y's will be the number of viewers. Let's denote them by A = (x₁, y₁) and M = (x, y), respectively. Say that currently, you have 54,000 subscribers, and let's try to translate all this data in such a way that the endpoint calculator will understand what we want from it.Īccording to the above section, in order to find the answer, we need the starting point and the midpoint. In other words, the endpoint will be our answer. Now, we're at month four, which will be our midpoint (since we want to find the number of viewers in another four months). After all, the starting point, i.e., month zero, was when you began posting the videos, so we were at 0 viewers at that point. Why don't we try to find the missing endpoint with our calculator to check how many there should be in four months?įirst of all, note that although the problem doesn't seem geometrical at all, we can indeed find the answer using the endpoint definition from geometry. It started as a hobby, but people seem to be enjoying the show, and you see the number of viewers increasing linearly with time. Nothing fancy, just a few cooking recipes that are traditional to your region. Say that four months ago, you began posting videos on YouTube. To sum it all up, if you like having all the information you need in one paragraph, then there it is. Or, if you'd like to sound fancy, by the vector A M AM A M. This means that to find B B B, it is enough to ' move' M M M along the line going through A A A and M M M by the same length as that of the segment A M AM A M. It's just that B B B is on the other side. We will now explain how to find the endpoint B = ( x 2, y 2 ) B = (x_2, y_2) B = ( x 2 , y 2 ) if we know the midpoint M = ( x, y ) M = (x, y) M = ( x, y ).įrom the definition of a midpoint, we know that the distance from A A A to M M M must be the same as that from M M M to B B B. Say that you have a line segment going from A = ( x 1, y 1 ) A = (x_1, y_1) A = ( x 1 , y 1 ) to. For instance, they appear in the endpoint formula. What is more, the coordinates help us analyze more complicated objects in our Euclidean space. Together, such a pair of numbers ( x 1, y 1 ) (x_1, y_1) ( x 1 , y 1 ) defines a point in the space. The numbers x 1 x_1 x 1 and x 2 x_2 x 2 mark the position of the points with respect to the horizontal axis (usually denoted with x x x's), while y 1 y_1 y 1 and y 2 y_2 y 2 are used for the vertical axis (most often denoted with y y y's). It's not too important right now to understand its mathematical definition, but, for our purposes, it's enough to know that this means that in such spaces, points, say, A A A or B B B, have two coordinates: A = ( x 1, y 1 ) A = (x_1, y_1) A = ( x 1 , y 1 ) and B = ( x 2, y 2 ) B = (x_2, y_2) B = ( x 2 , y 2 ).

In coordinate geometry, we handle objects that are embedded in what we call Euclidean space. (Yes, that was a terrible joke, and we bow our heads in shame. After all, you need a ruler for that, and Lorde is hard to come by. However, there are people (and we're not suggesting that we are those people) that don't really enjoy drawing lines that much. Measure the distance from A A A to B B B and mark the same distance from B B B going the other way.Draw a line going farther from B B B away from A A A to God-knows-where.

Given the starting point, A A A, and the midpoint, B B B, draw the line segment that connects the two.

Therefore, intuitively, we can already geometrically describe how to find the endpoint. This is all that we need to find the endpoint after all, it must lie at the other end of the midpoint from the starting point and be the same distance away. The latter is simply, as the name suggests, the point marking the middle of the segment. The simplest and most common situation is where we're missing the endpoint while we know the starting point and the midpoint. In other words, since we're dealing with a line segment and one of its components, we need to know what the rest of it looks like. In order to get the endpoint, we need to have some point of reference to begin with.
