Question: (a) Find the arc length function for the curve measured from the point P in the direction of increasing t and then reparametrize the curve

(a) Find the arc length function for the curve measured from the point P in the direction of increasing t and then reparametrize the curve with respect to arc length starting from P, and 

(b) Find the point 4 units along the curve (in the direction of increasing t) from P.r(t) = e' sin ti + e' cos tj + /2e' k, P(0, 1, /2)

r(t) = e' sin ti + e' cos tj + /2e' k, P(0, 1, /2)
