Calculator will crash, when analyze function 𝑦=|sin(𝑥)|+|cos(𝑥)|

[xvzhenduo]

Describe the bug 当在函数中分析𝑦=|sin(𝑥)|+|cos(𝑥)|时，计算器崩溃（闪退）。 Calculator will crash, when analyze function 𝑦=|sin(𝑥)|+|cos(𝑥)| .

Steps To Reproduce 1.打开计算器，进入侧边栏，点击函数 Open Calculator, go to Graphing mode. 2.输入函数 y=abs(sin(x))+abs(cos(x)) Input function y=abs(sin(x))+abs(cos(x)) 3.点击分析函数 Click "Analyze function" button.

Thanks for the bug report! I am not able to get the app to crash, but I do encounter an error preventing the expression from being plotted:

@grochocki I can reproduce the crash in my machine, the expression can be plotted.

Thanks for the bug report! I am not able to get the app to crash, but I do encounter an error preventing the expression from being plotted:

有时候经常出现这样的错误，你可以试着先重启应用，删除abs()绘制一下函数，然后再将abs()加上，在绘制函数就重现 (Translated by @tian-lt: It's a usual error sometimes, you can try restarting the App, remove operator abs() from the expression and plot it, then add abs() back, after that the expression can get plotted again.)

The "abs()" was written or copied and pasted or was used by the | x |? Because if it was written or copied and pasted it might have taken some unknown character. For example when a complete function is copied.
