3. An object moves so that at time t its position s is found using s(t) = 5-cos(t). a) For what values of 't' does the object change direction? b) What is its maximum velocity? c) What is its minimum distance from (0, 1)? 4. Are there any numbers x, 0 s x s 27t , for which tangents to f(x) = sin(x) and f(x) = cos(x) are parallel? If so, find the values
