    Solve for t

    Unsure how to show this as an equation. I tried looking for a help guide for this site, so I apologize and if anyone can direct me that would be great.

    But the problem is this.

    Solve y = 1/2 a t^2 for t

    The 1/2 is a fraction. I looked online and found many examples but all of them had addition signs and were not exactly like this. I am pretty stumped.

    Re: Solve for t

    If the question is only asking you to solve for t:

    Step 1:
    y = \frac{at^2}{2}

    Step 2:
    2y = at^2

    Step 3:
    \frac{2y}{a} = t^2

    Step 4:
    \sqrt{\frac{2y}{a}} = t

    And you're done.

    As for writing your math nicely, this forum uses LaTeX. There are plenty of guides for it online. To write your initial problem you would type: y = \frac{at^2}{2} with [ tex] before your equation and [ /tex] after it (minus the spaces).
