Q.Torsion is defined only when K(S)≠0 (why?)
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.
If a and b are non-collinear vectors and A = (x+y)a+(2x+y+1)b

A soft- drink vending machine is set to dispense 6 ounces per cup. If the machine is tested nine times, yielding a mean cup fill of 6.2 ounces with a standard deviation of 0.15 ounce, is this evidence at the level of significance 0.05 that the machine is overfilling cups?
Obtain all the first second order partial derivatives of the function f(x,y) = x^2 siny + y^2 cosx
