SUMMARY

The discussion focuses on rearranging the equation d = (1/2) a t^2 to solve for the variable 'a'. The steps include swapping sides, multiplying by 2, and dividing by t^2, leading to the final equation a = 2d/t^2. This process highlights the importance of isolating the variable on one side of the equation. The conclusion emphasizes the necessity of understanding algebraic principles for effective problem-solving.

To solve for something means to isolate that thing on the left side of the equation.

d = (1/2) a t^2
Swap sides,
(1/2) a t^2 = d
Multiply by 2, divide by t^2,
(2/t^2)*(1/2) a t^2 = (2/t^2) d
Clear fractions and reduce,
a = 2 d/t^2
and the equation is solved for a.

You really need to learn algebra!
