**F**=<2sin(x)cos(x), 0, 2z> along the path

**r**=<t,t,t

^{2}>, 0≤t≤π

To do the line integral, I need to find

**F**(

**r**(t)), but I don't understand how to express it. For example I looked at the online notes provided here: http://tutorial.math.lamar.edu/Classes/CalcIII/LineIntegralsVectorFields.aspx

I don't understand how
