How can I calculate $(x*k)/i$ (mod $m$) where i and m are relatively not co-prime ?
We know that, if $\gcd(i,m)\neq1$ , then there doesn't exist a modular multiplicative inverse of $i$ mod $m$. Then how can it be solved?
Thanks in Advance :)
How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
