y'(t) - ay(t) = 0

What is the form of the solution? C \cdot e^{at}

?I have this ODE:

T'(t) - (1 - \frac{n^2}{4})T(t) = 0

If I'm right, the solutions should be of the form

C \cdot e^{(1- \frac{n^2}{4})t}

My book, however, says C \cdot e^ {1- \frac{n^2}{4}t}

Who's right?

I think the book forgot some parentheses
 
Brilliant.

And how about the equation

y' = (y - x)^2

what's the form of the solution here?

I find it hard to determine the form of solution of differential equations.

I would try a simple substitution first. How about v=y-x? Now see if you can separate it in those variables.
 
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...
