    I use LaTeX environment.

    MikTeX (Compiler) + WinShell (IDE) + mpedit (not used here)

    It should be AF=75sec40

    so theta=17.4 dg.

    4Questions --> is that too many?

    2012-07-23 12:00:58 補充:

    typo.

    If you checked carefully, you see the question says (v,t)=(12,0)

    2012-07-23 12:01:45 補充:

    After all, it is tiring typing codes like:

    Put $(v,t)=(0,12)$ into $v=3\sqrt{\ds 16-s^2}$, $s=0$. Hence

    \begin{align*}

    0&=\fr{1}{3}\sin^{-1}0+c\\

    c&=0

    \end{align*}

    Then $s=4\sin 3t$. \\ \\

    in LaTeX without visualizing the result of codes

  • I mean the additional Q is not under the topic of "integration".

    Sorry for typo!

    2012-07-23 11:59:52 補充:

    v = 3√(16 - s²)

    Given when t=0, v = 12

    Therefore, when t = 0,

    12 = 3√(16 - s²)

    4² = 16 - s²

    s² = 0

    s = 0

    What do you mean by "not 'interation' " ?

    To 石石:

    What software do you use?

    2012-07-22 20:34:28 補充:

    It seems there's something wrong with your answer...

    2012-07-23 11:50:45 補充:

    I want to ask, in Q52,

    3√(16 - s²) = 0 ⇒ s = 0 ????

    s should be 4...
