(a) Evaluate the integral ∫2048x2+4dx. Your answer should be in the form kπ, where k is an integer. What is the value of k? (Hint: darctan(x)dx=1x2+1 ) k= 6 (b) Now, lets evaluate the same integral using power series. First, find the power series for the function f(x)=48x2+4. Then, integrate it from 0 to 2, and call it S. S should be an infinite series ∑[infinity]n=0an . What are the first few terms of S?

![=\int\limits^2_0 {\frac{48}{x^2+2} } \, dx \\\\=\frac{48}{2} [\tan ^-^1(\frac{\pi}{2}) ]^2_0](/tpl/images/0669/8583/5d782.png)
![=24[\tan ^-^1(1)- \tan^-^1(0)]\\\\=24(\frac{\pi}{4} )\\\\=6\pi\\\\ k \pi=6 \pi\\\\k=6](/tpl/images/0669/8583/cf217.png)
