Show work, will not give a thumbs upIf work is not shown.Do you consider that absolute or conditional convergence is the stronger, more useful form of convergence? Explain.Determine the interval of convergence of the power series which is the sum from n=0 to infinity of the terms an=[:n(x2)''3-1-1Are there power series which diverge everywhere? If so, exhibit one. If not explain why it cannot happen.Find the first three nonzero terms in the Maclaurin series of f(x)=tanx.
