Find the point in which the line x=1-t, y=3t, z=1+t; meet the plane 2x-y+3z=6

Find a unit tangent vector to r(t)=e^(2t)i+e^(-1)j+(t^2+4)k at (1,1,4).

which war did the most americans die - american revolutionary war?, WW1, US civil war? or WW2?

oh yes it is.

r(t)=e^(2t)i+e^(-t)j+(t^2+4)k at (1,1,4)

how does 1/e equal to 1? ∥r'∥ = √(4e^4 + 1 + 4)

oh ok, now i get it.
