# Proof of the irrationality of $\sqrt{2}$.
So I was thinking about how to prove the $\sqrt{2}$ is irrational while on holiday. (Bear in mind that at this point, I only knew that it was indeed irrational, not how to prove it.)
Anyway, I came up with my own proof with no knowledge of what "contradiction" was, this was... | HuggingFaceTB/finemath | |

The expression $g(x)$ has the same remainder constant $k$ when divided by $(x-a)$ or $(x-b)$. Determine, with reasons, whether it is always true that $g(x)$ also has remainder constant $k$ when divided by $(x-a)(x-b), k \neq 0$.
My proof:

# Why is the energy at a different frequency than the angular frequency in a simple harmonic oscillator?
I have a displacement function a simple harmonic oscillator: $$x(t) = A\cos(2\pi t),$$ The potential energy is then $$E_p(t) = \frac{1}{2} sA^2\cos^2(2\pi t),$$ where $s$ is the spring constant. So I have an angula... | HuggingFaceTB/finemath | |

# How to Solve for $x$ in a Particular Exponential Equation
I am trying to solve for $$x$$ in
$$x^2=(16)^{2x}.$$
So I started this way: I took square root of both sides and got
$$x=16^x$$
Then I took the logarithm of both sides and got $$\log x=x \log 16.$$
This is where I got stuck.
