How to Split Absolute Value in an Integral

Click For Summary
SUMMARY

The discussion focuses on the method to split the absolute value in the integral \(\int^1_{-1}\left| \frac{1}{2}+xt\right|dt\). The correct approach involves separating the integral into two parts based on the sign of the expression inside the absolute value. Specifically, it is split into \(\int_{-1}^0 -\left(\frac{1}{2}+xt\right) dt\) and \(\int_0^1 \left(\frac{1}{2}+xt\right) dt\). Visualizing the function by graphing \(\frac{1}{2}+xt\) is recommended for better understanding.

PREREQUISITES
  • Understanding of definite integrals
  • Knowledge of absolute value functions
  • Familiarity with piecewise functions

Homework Statement



How do split

\int^1_{-1}\left| \frac{1}{2}+xt\right|dt

Homework Equations





The Attempt at a Solution



\int_{-1}^0 -\frac{1}{2}-xt dt+\int_0^1 \frac{1}{2}+xt dt

Im not sure if this is right, and if it is... i still don't understand how to split the absolute value part inside an integral.

thank you

Do you know how to split up |t|? I suggest drawing a graph of 1/2+xt and look closely how it differs from |t|.
