Number of images formed by two plane mirrors formulae derivation.
2020年9月24日 · Number of images formed by two plane mirrors inclined at an angle of $\theta$ is given by $$\frac{360}{\theta} -1 $$ What I think: Inclined mirror forms images in the circle and one image lies in one sector. No of images = Number of sectors= $\frac{360}{\theta}$ And $1$ is subtracted from $\frac{360}{\theta}$ because a sector is occupied by the ...
How to get a reflection vector? - Mathematics Stack Exchange
So, the initial situation is $\vec{a}$ pointing toward a plane. Then we have the normal $\vec{n}$ of unit lenght and we would like to find $\vec{b}$ So, the first step is using the dot product to get a vertical vector that will be used in step 2.

2020年11月29日 · in fact, one can "mirror" any geometrical object with respect to a circle in 2D or a sphere in 3D using a transformation called "inversion" which is described here. The mirroring property can be seen on the example of the fish "reflected" with respect to his bowl.
geometry - How to find coordinates of reflected point?
Now, consider the unsigned perpendicular distance of this point from the line/plane: $$ d = \frac{Au +Bv +C}{\sqrt{A^2 +B^2}}$$ Now, depending on sign of the above quantity we can see which part of the plane/ line which the point is .
