"Reparametrize the curve with respect to arc length measured from the point where t = 0 in the direction of increasing t. (Enter your answer in terms of s.) r(t) = 3ti + (1 - 4t)j + (1 + 2t)k r(t(s)) ="

answer

Step-by-step explanation:

The step by step procedure is to first determine the differentiate the given vector function

r(t) = 3ti + (1 - 4t)j + (1 + 2t)k

since s(t) is the arc length for r(t), which is define as

if we substitute the value of r'(t) we arrive at

substituting the value of t in to the given vector equation we have

(3x-8) or (3x+8)

the correct option is b
