Practice problem
What is the interval of convergence for this series?
(−∞,2+3)(-\infty, 2 + \sqrt{3})(−∞,2+3)
(−2,2](-2, 2](−2,2]
(2−3,2+3)(2-\sqrt{3}, 2+\sqrt{3})(2−3,2+3)
[2−3,2+3][2-\sqrt{3}, 2+\sqrt{3}][2−3,2+3]
(−3,3](-\sqrt{3}, \sqrt{3}](−3,3]
Type a concept, like “slope” or “photosynthesis”.
