Dear Uncle Colin,
I have to solve $5^x = 6 - 5^{1-x}$ - I understand it’s going to end up as a quadratic, but I can’t see how!
- Explain, Uncle Colin, Like I Demand!
Hi, EUCLID and thanks for your message!
The key thing here is to spot that you can split up the last term as either $5 \times 5^{-x}$ or (equivalently... | {} |

# constructing a symmetric matrix for finite difference
I come across the following operator in a paper
$$\mathcal{I}\psi = \psi_{xxxx} + (r~\psi_x)_x$$,
where $$\psi=\psi(x)$$ and $$r=r(x)$$. Periodic boundary condition is employed. It claims that the operator $$\mathcal{I}$$ is symmetric. Suppose I use finite diff... | {} |

Question about a stretched string's motion at the free end
Main Question or Discussion Point
1. I don't know why ∂Ψ/∂x should be zero in (1.125). Shouldn't the tension be zero at the very last end?
2. I don't know why we can apply the results of the wave equation at the free end because we assumed there are tension b... | {} |
