    binomial expansion of (1+x)^n for values of n that are not positive integers

    I don't understand what the valid when x<1 means , can somebody explain to me please?

    Non-linear algrebra?

    Whilst attempting to prove a conjecture I've become completely stumped at one part. Anyone know what sort of math I should look at to solve for f given x^2 + y^2 + f(x,y)^2 = 2y + 2f(0,1)f(x,y) = 1 + f(0,1)^2 and given f(x,y) = ax + by I was trying to force it into a linear problem but...

    algrebra, log, I think im forgetting something

    i have an equation: y=Al^a and i need to solve for y/l. is this possible? I keep trying to use logarithms, but it is no use. Is there something clever I'm forgetting?
