Find r (t) satisfying the given conditions. (Remember to use In |u| where appropriate.) r' (t) = t + 1i + t/t2 + 2 + 2/t k; r(3) = i + j + 2k Find the integral. [4/1 + t2i + t/2 + 2t2 j - 5/ 1 - t2 k] dt

Find a vector equation for the line through the point P = (1, -2, -5) and parallel to the vector V = (- 2, 2, -4). Assume r(0) = 1i - 2j - 5k and that V is the velocity vector of the line. r(t) = i + j + k
