### Questions (20)

 5 why does this integral diverge? 3 Use mathematical induction to prove that 9 divides $n^3 + (n + 1)^3 + (n + 2)^3$; Looking for explanation, I already have the solution. 2 Can I further reduce this matrix? 2 Where am I making my mistake? (intervals of convergence) 1 Length of the curve defined by $y=6 x^{3/2} - 7$ from $x=1$ to $x = 9\;$?
