    Solving out an equation.

    A problem I'm doing calls for me to solve the equation when y=0. But my algebra skills are failing me, and I can't do it right. So could someone help me?

    Here's the equation:

    f(x)=-4.9sin((pi/6)t)*(pi/6)

    According to the hint, I'm supposed to end up with five answers.

    This does not strike me as an "algebra skills" problem. You must be sleeping through class or something. The only thing that might possibly be a problem is the sine and that is trivial with the simple concept fo the inverse sine.

    0 = -4.9 \sin((\pi/6)t)*(\pi/6)

    Get rid of the unhelpful constants

    0 = \sin((\pi/6)t)

    Now the inverse sine function.

    \sin^{-1}(0) = (\pi/6)t

    And that's zero.

    0 = (\pi/6)t

    More meaningless constants

    0 = t

    That looks like it.
