hey, the * is for multiplication. Overall we have: integral from negative infinity to positive infinity of ( u(t) times cos(t) dt) the solution manual says it's equal to 1. I thought it was equal to sin(t).

u0(t) is a step function. its "0" from negative infinity to t=0 and "1" from t=0 to positive infinity.

Hi there! I have a problem with one of the questions given to us in the signals and systems course. If anyone could help me I would greatly appreciate it! Homework Statement integral(from -infinity to +infinity) of u0(t) * cos(t) dt u(t) is a step function. Homework Equations...
