everyshi belongs to the ms bundle, which consists of several packages by Martin Schröder. If TeX Live or MiKTeX is used, you don't need to install everyshi as single package, such as by compiling everyshi.ins or everyshi.dtx. Instead, use the package manager (tlmgr or mpm, respectively) to install th... | {} |
# Definition of Multiple
A multiple is the result of multiplying one integer by another integer.
The number grid on the left shows all the multiples of $3$ (highlighted in yellow) between $1$ and $100$.
Some other examples are the following:
• $18$ is a multiple of $9$ as $9 \times 2 = 18$.
• $-12$ is a multiple of... | {} |

### MrOmar
Hello all, I am currently trying to solve a differential equation numerically. The equation is as follows:
dv/dt = (u*q)/(m0-q*t) - g - (cd*ρ*A*0.5)*v2
If you haven't already guessed, it's the rocket equation with added gravit... | {} |
