1. The problem is to find the formula for a given mathematical relationship or function. 2. A formula is an equation that expresses a relationship between variables. 3. For example, the formula for the area of a rectangle is $$A = l \times w$$ where $l$ is the length and $w$ is the width. 4. Another common formula is the quadratic formula for solving $ax^2 + bx + c = 0$: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ 5. To use a formula, identify the variables and substitute their values, then simplify step-by-step. 6. If you specify the type of formula or problem, I can provide the exact formula and detailed steps.
