Hello, I need help with one of my assignment questions. How do you calculate the diameter of a pipe needed to water a track with only knowing the flow rate of 0.7 l/sec

Q.Find equation of the osculating plane and osculating circle of the curve at the given point.

γ(t)=(2 sin3t, t, 2 cos3t), (0, π, -2)

γ(t)=(2 sin3t, t, 2 cos3t), (0, π, -2)

Q. Compute the torsion of the following curves

(i) γ(t)=4/5cos t, 1-sint,(-3)/5cos t

(ii) γ(t)=(t, cosht)

Q. Show that if curvature K(t) of a regular curve γ(t) is >0 every where, then k(t) is a smooth function of t. Give an example to show that this may not be the case without the assumption that k>0.
