Determine if the vector-valued function has a limit at the specified point. Determine if the function is continuous at the specified point. (Your instructors prefer angle bracket notation> for vectors. If the limit exists enter the limit. If the limit does not exist enter DNE.) cos(t) (a) F(t)-? -, tan(t), 4t-4) at to ?
