如何在对齐模式下添加换行符？

Question

抱歉，看上去太乱了，但在代码中，我在想要换行的地方放了一行加号。我该怎么做呢？

\begin{align}  
$$\bigg|f\bigg(\displaystyle \frac{1}{2}\bigg)-P\bigg(\displaystyle \frac{1}{2}\bigg)\bigg|\leq \displaystyle \frac{1}{100}  
+++++++++++++++++++++++++++++++++++++++++++++++++++++++  
\bigg| f\bigg(\displaystyle \frac{1}{2}\bigg)-P\bigg(\displaystyle \frac{1}{2}\bigg)\bigg|\leq \max_{0\leq c \leq\frac{1}{2}} \bigg|\displaystyle \frac{f^{(5)}(c)}{5!}\bigg|\displaystyle \bigg(\frac{1}{2}\bigg)^{5}$$  
\end{align}

Answer 1

使用以下编码来满足您的要求：

\begin{align}
& \bigg|f\bigg(\displaystyle \frac{1}{2}\bigg)-P\bigg(\displaystyle \frac{1}{2}\bigg)\bigg|\leq \displaystyle \frac{1}{100}
\\ \nonumber 
& \bigg| f\bigg(\displaystyle \frac{1}{2}\bigg)-P\bigg(\displaystyle \frac{1}{2}\bigg)\bigg|\leq \max_{0\leq c \leq\frac{1}{2}} \bigg|\displaystyle \frac{f^{(5)}(c)}{5!}\bigg|\displaystyle \bigg(\frac{1}{2}\bigg)^{5}
\end{align}
