## MathSofiya Group Title I'm try to strip out a term to have the sum start at n=0 but it turns out that I don't have to anything...I still don't understand why =/ $0+\sum_{n=1}^\infty a_n nx^n=\sum_{n=0}^\infty a_n nx^n$ 2 years ago 2 years ago

11. mahmit2012

12. MathSofiya

Yeah the series is solved
