Its when you have an equation and you have to prove its true for every n. for n=positive interger.
so u put in the equation n+1 and then u prove it that way...
So what is this type of math called??
I dunno what it is called in English... Though I fail to see how putting n+1 in the equation would proof such an equation....
You just need to solve the equation in such a way that n is on the left of the equation and something else is on the right of the equation, where the equation is actually a "greater than" sign...
eg: solve it so you come to something like "n > 0".
eg: is
n*8 > n always true if n=postive integer? yes, proof:
1) n*8 > n
2) (n*8)-n > n-n
3) n*7 > 0
4) n*7/7 > 0/7
5)
n > 0
if that is what you meant

We just call Function of X or... F of X for short... (derived function is probably the mathematical term for it though.
function of X is correct for f(x)... but note the
' after f(x), which means f(x)' is the
derived function of x.
The ' wasn't a typo in his post...
