I really don't think that such tags are focused enough to be of any real use to the site. They are highly unlikely to be uniformly applied, and so their value as search aids would be negligible, at best.

Let $P$ be a plane in $\mathbb{R}^3$ that is inclined (neither horizontal nor vertical). When considering lines lying on $P$, it is sometimes said "$L$ is a line of greatest slope of $P$". What is the meaning of the term "line of greatest slope"?

I'm writing a program in which it is possible to draw a horizontal, vertical or an oblique line. So the line can be described as follows : $f(x) = y = mx + q$ But my problem is that given the first point, the last point and a point on the line I have to compute the next point. With "next point...

I have see a few proofs that, in some systems, a circle with infinite radius is a straight line. A nice example of this is stereographic projection in the complex plane. I have also see simple proofs where people make a circle converge to a vertical line. However this is slightly unsatisfying to ...

I have one math problem which I'm trying to solve. I know it could be done but I'm a little bit "rusty" with my algebra. I'm kindly asking for help. Problem and procedure of my solution are shown in attached image. I'm trying to find general solution for line equation (points $1$ and $2$ lie on ...

I have the coordinate $X$ and $Z$ of a point $M$. I need the $Y$ coordinate of this point knowing that the point is on a line defined in space by $A(X_1,Y_1,Z_1)$ and $B(X_2,Y_2,Z_2)$. Thank you

Compute the distance between the point $ X(t) = (1 + \cos(t), \sin(t), 2\sin(\frac t2)) $ and the line passing through the points $(1, 0, 0)$ and $(1, 0, 1)$.

I'm totally lost. I've been trying to figure this out. This is what I've figured out: $dy/dx = 1/x$ $y$-intercept $= 1$ So I try to do $y-y_1 = m(x-x_1)+b,$ which I get as $y-1 = 1/x(x-0)+1,$ simplified to $y = 3.$ But I feel like that is totally wrong and well, obviously it isn't even an equ...

In the program I'm developing, there are a large number of lines, and one point. One of the lines will split into two lines, the first line beginning with the original's first point and ending with the loose point, and the second beginning with the loose point and ending with the original's secon...

Suppose $u$ and $v$ are points on the unit circle such that the line through $u$ and $v$ intersect the real axis. Show that if $z$ is the point where this line intersect the real axis, then $$z=\frac{u+v}{uv+1}.$$
