We don't actually use displacement as a function, because displacement requires a time interval, whereas a function gives instants in time. The derivative of the vector-valued position function x (t) is the "rate of change of position", also known as velocity v (t).
Explain the significance of the net change theorem. Use the net change theorem to solve applied problems. Apply the integrals of odd and even functions. In this section, we use some basic integration formulas studied previously to solve some key applied problems.

Just as we did before, we can use definite integrals to calculate the net displacement as well as the total distance traveled. The net displacement is given by
20 lip 2022 · dAtt1 dt = lim Δt → 0ΔAtt1 Δt = lim tc → ta(tc) = a(t) with the initial condition that when t = t1, the area At1t1 = 0 is zero. Because v (t) is also an integral of a (t) , we have that. Att1 = ∫a(t)dt = v(t) + C. When t = t1, the area At1t1 = 0 is zero, therefore v(t1) + C = 0, and so C = − v(t1).
How to Find Total Distance. Most distance problems in calculus give you the velocity function, which is the derivative of the position function. The velocity formula is normally presented as a quadratic equation. You can find total distance in two different ways: with derivatives, or by integrating the velocity function over the given interval.
Using integral calculus, we can work backward and calculate the velocity function from the acceleration function, and the position function from the velocity function. Kinematic Equations from Integral Calculus. Let’s begin with a particle with an acceleration a(t) which is a known function of time. Since the time derivative of the velocity ...
