I have this question due soon and I have no idea how to do it. Please help me get started on it

Solve in powers of x: (1-x^2)y''-2xy'+42y=0

Re: Solving in powers

The equation:

$$\left(1-x^2\right)y''-2xy'+n(n+1)y=0$$

where $n\in\mathbb{N}$ is called Legendre's differential equation which has as solutions:

Legendre polynomials

That should give you a place to start. :D
 
Thank You, Mark! I'll try working on it and reply with any problems I have
 
I have the equation ##F^x=m\frac {d}{dt}(\gamma v^x)##, where ##\gamma## is the Lorentz factor, and ##x## is a superscript, not an exponent. In my textbook the solution is given as ##\frac {F^x}{m}t=\frac {v^x}{\sqrt {1-v^{x^2}/c^2}}##. What bothers me is, when I separate the variables I get ##\frac {F^x}{m}dt=d(\gamma v^x)##. Can I simply consider ##d(\gamma v^x)## the variable of integration without any further considerations? Can I simply make the substitution ##\gamma v^x = u## and then...
