@math.with.tamar: How to solve an optimization problem using derivatives. 1. Draw a picture 2. Write out your given 3. Write out the function you are minimizing or maximizing 4. Put the function from the step above in terms of one variable on the RHS 5. Find the absolute min/max by looking at critical values and endpoints 6. Show that the critical value is at a min/max by using first or second derivative test 7.
