Try another version of this question Express the series in terms of elementary functions and find the radius of convergence of the sum. `sum_(n=0)^(oo) (x^n - x^(2n+1))=`
Radius of Convergence:
Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Box 2: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Box 3: Enter your answer as an integer or decimal number. Examples: 3, -4, 5.5172
