1. The problem statement, all variables and given/known data If xy^2 = 12 and dy/dt = 6, find dx/dt when y = 2. 2. Relevant equations 3. The attempt at a solution My teacher wants us to follow a five step method for solving related rates: Step 1 [Information]: Assign variable letters to known and unknown quantities xy^2 = 12 dy/dt = 6 dx/dt = ? y = 2 Step 2 [Formula]: Find or develop a formula that relates the main variables in the problem Step 3 [Variable Check]: Eliminate variables, if possible*: i) substitute constant values** or ii) use another relation between the variables Step 4 [Differentiation]: Differentiate the formula with respect to time, and solve for he unknown rate. Step 5 (solving): substitute known (instantaneous) values, calculating them from given info, if necessary. Step 6 (answer): state the answer to the problem I'm not sure where to go from step 2.
