Evaluate the integral LIVITA using the two following different methods. a) Rewrite this integral as f de and use the following triangle to create a trig substitution. √x6+4 dr √x6 +4 2 Hint: Use tan(0) = 2 to find do. b) Rewrite the integral as S6 partial fraction decomposition. Note: The next page is left blank as extra space for this problem. Also, your solutions to (a) and (b) will likely look different, though if you've done everything correctly, they will be equivalent. de and use the change of variables u = √6 + 4 followed by
