What math symbol would I use for "never equal to"
alright so I know that [tex]1\neq 2[/tex] means that "1 is not equal to 2" right?
so could I say that [tex]e^x\neq 0[/tex]. Would this mean that e^x is never equal to 0? I know it seems small, but it confuses me a bit.
also what would I say if I had a function of another function, where the first function is not true if the second function is equal to some value, if that makes any sense.
Like if I said [tex]f(g(x))\neq 0 , g(x)=k[/tex] would that be saying that f(g(x) is not equal to zero as long as g(x) is equal to some number?
I've tried searching this and am just really confused. I have to start learning this stuff because my homework is slowly getting filled with all of these upside down v's and backwards E and stuff!
