        dx / dy = x / y so replace dy = dx * y / x

        --- Equation 2 ---
        Equation 1 = (sqrt(xy + 2ydx + dx^2 * y / x) - sqrt(xy)) / sqrt(xy)

        Multiply by sqrt(x) / sqrt(x)
        Equation 2 = (sqrt(x^2y + 2xydx + dx^2 * y) - sqrt(x^2y)) / sqrt(x^2y)
                   = (sqrt(y)(sqrt(x^2 + 2xdx + dx^2) - sqrt(x^2)) / (sqrt(y)sqrt(x^2))
        
        sqrt(y) on top and bottom cancels out

        --- Equation 3 ---

        = (sqrt((x + dx)^2) - sqrt(x^2)) / sqrt(x^2)  
        = ((x + dx) - x) / x
        = dx / x

        Since dx / dy = x / y,
        dx / x = dy / y

        (L1 - L0) / L0 = dx / x = dy / y

        Let's find dx, dy such that

        where
        v = f(dx, dy) = sqrt(dxdy)

        --- Equation 1 ---
        v = s / T * L
        sqrt(dxdy) = s / T * sqrt(xy)

        Amount of liquidity to remove must not change price so 
        dx / dy = x / y

        replace dy = dx * y / x
        sqrt(dxdy) = sqrt(dx * dx * y / x) = dx * sqrt(y / x)

        Divide both sides of Equation 1 with sqrt(y / x)
        dx = s / T * sqrt(xy) / sqrt(y / x)
           = s / T * sqrt(x^2) = s / T * x

        (L1 - L0) / L0 = (sqrt((x + dx)(y + dy)) - sqrt(xy)) / sqrt(xy)
        
        dx / dy = x / y so replace dy = dx * y / x

        --- Equation 2 ---
        Equation 1 = (sqrt(xy + 2ydx + dx^2 * y / x) - sqrt(xy)) / sqrt(xy)

        Multiply by sqrt(x) / sqrt(x)
        Equation 2 = (sqrt(x^2y + 2xydx + dx^2 * y) - sqrt(x^2y)) / sqrt(x^2y)
                   = (sqrt(y)(sqrt(x^2 + 2xdx + dx^2) - sqrt(x^2)) / (sqrt(y)sqrt(x^2))
        
        sqrt(y) on top and bottom cancels out

        --- Equation 3 ---
        Equation 2 = (sqrt(x^2 + 2xdx + dx^2) - sqrt(x^2)) / (sqrt(x^2)
        = (sqrt((x + dx)^2) - sqrt(x^2)) / sqrt(x^2)  
        = ((x + dx) - x) / x
        = dx / x

        Since dx / dy = x / y,
        dx / x = dy / y

        Finally
        (L1 - L0) / L0 = dx / x = dy / y

        Proof
        Let's find dx, dy such that
        v / L = s / T
        
        where
        v = f(dx, dy) = sqrt(dxdy)

        --- Equation 1 ---
        v = s / T * L
        sqrt(dxdy) = s / T * sqrt(xy)

        Amount of liquidity to remove must not change price so 
        dx / dy = x / y

        replace dy = dx * y / x
        sqrt(dxdy) = sqrt(dx * dx * y / x) = dx * sqrt(y / x)

        Divide both sides of Equation 1 with sqrt(y / x)
        dx = s / T * sqrt(xy) / sqrt(y / x)
           = s / T * sqrt(x^2) = s / T * x

              Contract address deployed with create is computed in the following way.

              contract address = last 20 bytes of sha3(rlp_encode(sender, nonce))

              where sender is the address of the deployer and nonce is the number of transactions sent by sender.

              Hence it is possible to deploy different contracts at the same address if we can somehow reset the nonce.

              Most ERC20 have the permit function to approve a spender if a valid signature is provided.

              However WETH does not. Surprisingly, when permit is called on WETH, the function call will execute without any errors.

              This is because the fallback inside WETH is execute when permit is called.
