括号太长了LaTeX代码怎么优化

青青子衿

感觉中括号太长了
\[ \frac{\partial}{\partial y}\left[\frac{\ln\left(\dfrac{\sin\frac{x+y}{2}}{\cos\frac{x-y}{2}}\right)}{\cos x}\right]=\dfrac{1}{\sin x+\sin y} \]

稍微换一下写法不就好了，比如
\[ \frac{\partial}{\partial y}\left[\frac1{\cos x}\ln\left(\dfrac{\sin\frac{x+y}{2}}{\cos\frac{x-y}{2}}\right)\right]=\dfrac{1}{\sin x+\sin y} \]

这样的怎么办呢？
\begin{align*}
\left\{

\begin{align*}
\left\{

X=...(x+A/...)
Y=...(1-B/...)
其中
