Question

How to turn y=ao(1-x^2+5/3x^4-3x^6+39/7x^8)+a1(x-3/2x^2+21/8x^5-231/48x^7) to series form? (Wait a minute, let me post a link.)

Answer 1

\[y=a _{0}(1-x^2+\frac{ 5 }{ 3 }x^4-3x^6+\frac{ 39 }{ 7 }x^8)+a _{1}(x-\frac{ 3 }{ 2 }x^3+\frac{ 21 }{ 8 }x^5-\frac{ 231 }{ 48 }x^7)\]

Answer 2

How to turn the above thing into the thing in attachment?

Answer 3
