Recall the power series expansion for = E=o(-1)"x"= 1-x+x² - x³ + ...on the interval(-1, 1). 1+x i. Use the given expansion to derive a power series expansion for 1 1+x2 Show at least 4 non-zero terms. ii. iii. Use the expansion in part (i) to find a power series expansion for tan¹(t) = f₁2dx. 1+x² Show at least 4 non-zero terms. Use the expansion in part (ii) to approximate tan-¹ (0.1) to within 0.000001. Round your answer to 6 decimal places.
