- Working directly from the definitions (and without using theCauchy Completeness Theorem) show that any Cauchy sequence of complexnumbers is bounded.Prove formally whether the given sequence has a limit, using the Cauchy criterium. If the sequence is properly divergent prove it formally too.Prove that limit x goes to 2 x^(3)+3 = 11 (Using epsilon-delta proof)
