Triangle Inequality, Integrals

Click For Summary
SUMMARY

The discussion confirms that the inequality |\int f(x)dx| < \int |f(x)|dx holds true in general, relating to the Triangle Inequality in the context of integrals. The reasoning provided is based on the established fact that -|f(x)| ≤ f(x) ≤ |f(x)|, which supports the validity of the inequality. This conclusion is significant for those studying mathematical analysis and integral calculus.

Is it true in general that:

[tex]|\int f(x)dx| < \int |f(x)|dx[/tex]

Not sure if "Triangle Inequality" is the right word for that, but that seems to be what's involved.

It is true in general simply because -|f(x)|≤f(x)≤|f(x)|.
