Hard derivative
How are you supposed to take the derivative of this?
y = (cx)/[(cx)²+(x²-k²)²]^.5

Re: Hard derivative
Just use the quotient rule?
There will be some reeeally ugly algebra to simplify, and you will need to use the chain rule twice (or the chain rule and the product rule) when you differentiate the bottom.
