Find T(t), N(t), at, and an at the given time t for the space curve r(t). (Hint: Find a(t), 7(t), at, and an. Solve for N in the equation a(t) = att + ONN.] (If an answer is undefined, enter UNDEFINED.) Function Time r(t) = 5ti - tj + t2k t= -1 T(-1) = N(-1) = at = an Viewing Saved Work Revert to Last Response Submit Answer
