## Homework Statement

[tex]y=e^{-t}Cos(t)+e^{-t}Sin(t)[/tex]

Find the smallest T such that |y(t)| < 0.1 for t > T

## Homework Equations

none

## The Attempt at a Solution

This question is actually a second part to a differential equations problem, the equation above being my correct solution to a second order linear equation. Now, in my attempt to solve this part, I am stuck because I am not sure what T is (as opposed to t). You have all the info the book has given me so does anyone know what T may be referring to?
