In summary, rearranging formulas is a useful technique in solving for a desired variable in scientific and mathematical calculations. This is achieved by isolating the variable using inverse operations. Any type of formula can be rearranged as long as the rules of algebra are followed and the equation remains balanced. Some common mistakes to avoid include not using inverse operations, incorrectly distributing terms, and not simplifying fractions or radicals. To ensure a correct rearrangement, one can check their work by substituting the rearranged equation into the original formula and confirming the equality of both sides.

Ok this is a veryyyyyyyy simple question.

d= vt + at^2/2 (motion equation)

I want to find a (acceleration)

2d -vt/t^2 = a

is this the right way?

You are close, but you have some silly mistakes. Be careful when you multiply.
 

1. What is the purpose of rearranging formulas?

Rearranging formulas allows us to manipulate equations and solve for a desired variable. This is especially useful in scientific and mathematical calculations.

2. How do you rearrange a formula?

To rearrange a formula, you must isolate the desired variable on one side of the equation by using inverse operations.

3. Can you rearrange any type of formula?

Yes, you can rearrange any type of formula as long as you follow the rules of algebra and maintain the equality of the equation.

4. What are some common mistakes when rearranging formulas?

Some common mistakes include forgetting to use inverse operations, incorrectly distributing terms, and not simplifying fractions or radicals.

5. How do you know if you have correctly rearranged a formula?

You can check your work by plugging in your rearranged equation into the original formula and verifying that both sides of the equation are equal.
