yes, it is relevant...firstly, u should understand why \displaystyle\lim_{n\rightarrow \infty} ((1 + \frac{1}{n})^{n}) = e then u can solve this question easily..

it will be easier to solve this question using Newton-Raphson method. :)

i mean if no restriction answer = 60, then when there is a restriction answer will be < 60...

IF the number that can be used is only 0, 1, 3, 5, 7, without any restriction, the numbers of equations that can be formed at most are only 5P3=60, right? So, do u think it means 10, 37, 137,... those numbers can be be used?

the standard quadratic equation is f(x) = a(x - h)2 + k

so, i get this... a=0 when b\ne 0 b=0 when a\ne 0 ab=0 when a\ne 0 and b\ne 0 then, i get nothing here... so, what does it mean? Am i approaching the wrong way?

Homework Statement How to show that there exist no function f,g:R\nearrowR satisfying f(x)g(y)=x+y, for all real x,y? Homework Equations Any equation for showing function? The Attempt at a Solution how about starting with sumthing like let h(x,y)=x+y ??
