For the curve defined by 7(t) = (e-t, v2 - t, e*) find the unit tangent vector and unit normal vector at t = 0. Hint 1: 7'(t)| can be simplified. Try using the rule a? + 2ab + b2 = (a + b)². Hint 2; You will need quotient rule to calculate T'(t). Hint 3: T'(t) is the final derivative you need to complete the problem. Plug in t = 0 after finding T'(t) but before finding T'(t). T(t) = Ñ(t) = B(t) =
