Homework Statement



Differentiate:

y'''+ty''+y'+y'=0

Homework Equations





The Attempt at a Solution



I tried to use this definition:

(y')'=y''

I'd be thankful, if somebody could show me the rules of differentiating y'.

You've got it. (y')'=y'', (y'')'=y'''. Etc. Don't forget to use the product rule on ty''.
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
