y=a+b*x+c*x^2+d*x^3+e*x^4...
y'=b+2c*x+3d*x^2+4e*x^3 and so on ...you equate multipliers in both sides of DE...
Hi all,
So I am just wondering if anyone can confirm that the following is a solution of the DE. I'm not entirely sure how to differentiate a factorial so I am at crossroads for checking to see if it satisfies the DE. This was a question off an exam I wrote this morning, and I'm just wondering if that solution is indeed correct.
Solution =
Thanks in advance!
