# How to graphically find integral of square of signal.

Say we have a signal $x(t)$, then integral of $x(t)$ is the area under the curve. But integral of $x^2(t)$ is not simply square of that area!

Is there any way to graphically find integral of $x^2(t)$? For any $x(t)$.

• You need to integrate, there is no shorter method imo – samjoe Nov 5 '17 at 3:39
• No, I believe its impossible to do in general. – EzWin Nov 5 '17 at 6:12
