AP Calc Free Answer Problem:Change Over Time

  1. Jan 27, 2008 #1
    1. The problem statement, all variables and given/known data
    A Particle Moves along the x-axis so that its velocity v at time t [tex]\geq[/tex] 0 is given by v(t)=Sin(x[tex]^{2}[/tex]). The Graph of V is shown above for 0 [tex]\geq[/tex] t [tex]\geq[/tex] [tex]\sqrt{5\pi}[/tex]. The Position of the particle at time t is x(t) and its position at time t=0 is x(0)=5

    2. Relevant equations
    Find the total Distance traveled b the particle from time t=0 to t=3.


    3. The attempt at a solution
    1. The problem statement, all variables and given/known data
    We just started on integration so i figured we would need find the displacement equation by integrating the velocity equation, which would be finding:
    [tex]\int[/tex] Sin(x[tex]^{2}[/tex] dt [0,3]. From here i have no idea how to do the equation since we're only 2 weeks into integration and have barely touched [tex]\mu[/tex] Substitution

    The only way I can see to do it is to take the taylor series of sinx and replace all the x's by x^2 and then approximate the terms.

    oh thanks, in your opinion do you think that this problem is quite difficult for an AB AP Calculus Class?

    If the graph of the velocity is given, can you use this alone to find the distance? Remember the original definition of the integral of a function!

    [also remember that as in real life, not all information available to you need be relevant.]

    Oh. Are you referring to a of a Rieman's Sum approach to solving the equation by means of RRAM/MRAM/LRAM, Simpsons, Trapezoidal rule?
