I'm reading modern physics, Tipler 5th edition, pages 21 and 22, and I'm not understanding how the differentiation was done from the position to find the velocity.
Equation for position: x'= y(x - vt)
y is the gamma constant.
Then in the first step to find the velocity, a derivative was done...
Homework Statement
In my physics homework, I ran into a differential equation. I am attempting to solve this differential equation for y(x).
Homework Equations
y''[x] = -C/(y[x]^3) - y[x]
C is a constant
The Attempt at a Solution
dy^2/dx^2 = -C y[x]^-3 - y[x]
(1)/(-Cy[x]^-3 - y[x]) dy^2=...
