# If $x$ and $y$ are acute, and $\sin y = 3 \cos (x+y) \sin x$, then find the maximum value of $\tan y$
Given $$x,y$$ are acute angles such that $$\sin y = 3 \cos(x+y)\sin x$$ Find the maximum value of $$\tan y$$.
Attempt: We have
\begin{aligned} 3(\cos x \cos y - \sin x \sin y) \sin x & = \sin y \\ 3 \cos x \sin ... | {} |

## 35.27 Properties of morphisms local in the fpqc topology on the source
Here are some properties of morphisms that are fpqc local on the source.
Lemma 35.27.1. The property $\mathcal{P}(f)=$“$f$ is flat” is fpqc local on the source.
Proof. Since flatness is defined in terms of the maps of local rings (Morphisms, D... | {} |

## Simplifying algebraic fractions (GCSE algebra)
Towards the end of a GCSE paper, you're quite frequently asked to simplify an algebraic fraction like: $\frac{4x^2 + 12x - 7}{2x^2 + 5x - 3}$ Hold back the tears, dear students, hold back the tears. These are easier than they look. There's one thing you ... | {} |
