Re: differentiation
If you can differentiate most things then this one shouldn't be a problem for you.
The 2 that you're dividing by is just a constant, so you don't need to worry about that.
As for x^4, just differentiate it like you would anything else. Multiply by the power, take one from the power, done.
So x^4 becomes 4x^3 and then you put the constant back in to produce 2x^3.
Why did the vector cross the road?
It wanted to be normal.
