1. (18 points) Let u(t) be a differentiable vector function such that |u(t)| = 1 for all t. You may assume that u(t) is defined for all t. Define the scalar functions f(t) and g(t) as follows: f(t): +3 +2t² - 3t+7 = 3 d g(t) = compu(t) dt ( f (t)u(t)]) Find the value of t where g(t) reaches its maximum.
