Prove that `1^2+2^2+dotdotdot+n^2>(n^3)/3,``n in N`

Text Solution

AI Generated Solution

To prove that \(1^2 + 2^2 + \ldots + n^2 > \frac{n^3}{3}\) for \(n \in \mathbb{N}\), we will use the formula for the sum of squares and compare it to \(\frac{n^3}{3}\). ### Step-by-step Solution: 1. **Write the formula for the sum of squares**: The sum of the squares of the first \(n\) natural numbers is given by the formula: \[ S = 1^2 + 2^2 + \ldots + n^2 = \frac{n(n + 1)(2n + 1)}{6} ...
