Let u(t) = 3t³i + (t² − 6) j − 2k and v(t) = e ¹i+5 e ¯¹j - e 5tk. Compute the derivative of the following function. u(t).v(t) Select the correct choice below and fill in the answer box(es) to complete your choice. A. The derivative is the scalar function B. The derivative is the vector-valued function ()i + ( )j + (_) k.

- Suppose u and v are differentiable functions at t = with u(à) = (0,2,1), u'(x) = (0,2, − 2), v(í) = (0, −5, − 2), and v'(í) = ( − 3,2,3).
