Extreme values Ex.1

1. Insert S(t) = 10t + 18t² - 2t³ in the Input bar to draw the function and press on the Enter key 2. Insert v(t)=Derivative[S] in the Input bar to draw the derivative of the function and press on the Enter key 3. Insert Extreme= Extremum[v] in the Input bar to find the maximum of the function of derivative and press on the Enter key 4. See that the maximum speed is achieved at 3 s and is 64 m/s
