Key Concepts: - If you know the rate of change of a function, and you want to find the total change of the function from X = a to X = b, you would find the under the rate of change function from X = a to X = b. - For example, if v(t) represents the velocity of an object from t = O to t = 6, sketch y = v(t) and find the total distance travelled by the object if: v(t)=4 v(t)= it v(t)= :t+6 Distance = Distance = Distance =
