    May I ask one thing?

    Hi all

    I am sorry to bother you.
    Could you help me to solve this problem?

    particle's moves in a straight line, whose velocity can be modelled by the
    following function
    v(t) = tsin(t):
    Find the distance s, covered by the particle from time t = 0 to t = 2 pie. Sketch
    the graph for v(t) over the domain [0, 2 pie], and display what the value of s
    represents on your sketch. Hint: recall s(t) = v(t), also think about the sign
    of the function v(t) for t > pie.

    Thanks a lot.

    $\displaystyle \displaystyle \begin{align*} d = \int_a^b{v(t)\,dt} \end{align*}$
