17. Find the linearization of the function f [1:] = tan(:.:) at I = E and then use it to approx- innate tan[4}. Hint: Note that 1\" = in\" 130 radian. t _ 1+t21 13. A particle moves along the xaxis, its position at time t given by :1: (t) t :2 0, where t is measured in seconds and :c in meters. (a) Find the velocity at time t. (b) When is the particle moving to the right? When is it moving to the left? {c} Find the total distance traveled during the rst 4 s. Hint: (c) |s(1) s(]| + M4] 3(1)| = 1;\"2 + {1J2 4J1?) = 13f1'r
