# One overall subscript with double integral?

I want to assign only one overall subscript that cover the both integral symbols in double integration, I tried:

$$T_y=\iint_A \tau_{xy}\,dA=0$$


but it only goes with second integral?

• Of course it does. – Johannes_B Dec 25 '15 at 13:21

You can use \limits to accomplish the job. The package mathtools provides good enhancements to the basic features of LaTeX typesetting.
