Use this list of Basic Taylor Series to find the Taylor Series for f(x) = 2x 1+x2 based at 0. Give your answer using summation notation and give the largest open interval on which the series converges. (If you need to enter ∞ , use the ∞ button in CalcPad or type "infinity" in all lower-case.) The Taylor series for f(x)= 2x 1+x2 is: ∞ k=0 The Taylor series converges to f(x) for |x|< . Use the Taylor series you just found for f(x)= 2x 1+x2 to find the Taylor series for ln(1+x2) based at 0. Give your answer using summation notation and give the largest open interval on which the series converges. The Taylor series for ln(1+x2) is: ∞ k=0 The Taylor series converges to ln(1+x2) for |x|< .

PARKS Anika is hiking on a rectangular trail at the national park. There are four resting spots along the corners of the trail. On the map, they are marked with coordinates of (-2, 2), (1, 2), (1, -2), and (-2, -2). If each unit represents 1 mile, find the perimeter of the trail in miles, using the coordinates.
