Conversion of coordinates (longitude ; latitude) to (X;Y)
We have an old mapping system we are needing to convert some data to and from.
We need to convert from Lng/lat to XY and from XY to Lng/Lat.
We can convert from Lng/Lat to XY Using the following:
MapWidth and MapHeight = 8192
x = (LngX + 180) *…

Proof of integral substitution rule
I have the proof of the integral substitution rule at the university. In order this rule to use, I must have some conditions. So $ f: I\to R$ and $g: I_0 \to I$ and $I,I_0$ are not trivial
intervals and $f,g$ are continuous and diffbars functions…

Basis of the polynomial with degree less or equal 2
Can u explain me one thing. We have
$P_2:= \{\text{all polynomial with degree}\leq 2\}$
and $U_0:=\{f \in P_2 \mid f(1)=0\}$
We have $f(1)=c_1+c_2+c_3$ (because every polymial has form of $ f(t)=c_1 +c_2\cdot t +c_3\cdot t^2.$
So we have as basis…

What is the name of this map projection?
Is there a name for the map projection that makes a circle out of a sphere, where, in polar coordinates, the angle is the bearing angle of the point and the radius is the distance (on the surface of the sphere) between the point and the point…
