Unformatted text preview: t ≤ 3. The position of the object at time t = 0 is one unit to the left of the origin. (a) Find the position of the object when t = 3. (b) Find the total distance traveled by the object during those three seconds. 2. Evaluate the deﬁnite integral Z π 4 sec 2 ( x ) √ 1 + 3tan x dx . 3. Find the indeﬁnite integral Z t 2 √ 1-tdt . 4. Sketch the region bounded by the curves y = sin x and y = sin2 x for 0 ≤ x ≤ π and ﬁnd its area. 5. Sketch the region bounded by the curves y = x 2 and y = 4. This region is divided into two subregions of equal area by the line y = c . Find c ....
