Integral from 20 to infinity of 0 dx?
The anti-derivative of zero is some constant; so, how do I do this?
Let thinks for a second... |dw:1401829247852:dw| That line I just labeled is y=0 And we want to look at it from 20 to infinity What does the integral from 20 to infinity of 0 represent?
|dw:1401829313642:dw| That arrow is to mean it continues
Don't integrals have something to do with area or net area?
I'm assuming the area under the line and the x-axis, which is nothing?
The area is nothing because you can't fit anything between the same line.
Ok, thank you very much!
