I've found every other critical point I need to, and this is essentially the last part I need. I have even used Wolfram Alpha to solve the equations, and have verified that the answers Wolfram Alpha gives are indeed the correct answers, and the solution to the system of equations that acts as a critical point, and my Absolute Minimum. If I write the before and after, and verify that it works, can I just put down "Used Wolfram Alpha" as my inbetween steps? The assignment sheet does say we can use a computer to solve equations...I'm just worried my solution won't be "clearly written and understandable by my fellow classmates."

I have looked for extrema in the whole unrestricted function, and found them without much difficulty, but for finding the extrema of the "edges" of the constrained area, I'm not sure how to apply our technique. By setting $\nabla f = \lambda \nabla g$, I get the two equations we need, but the third "equation" is actually the inequality we were provided with as a constraint. Can we use this inequality to solve for $x$ and $y$, or is there another method that I'm missing?DylanMon, 14 Jul 2014 22:12:00 -0500http://calc3.askbot.com/question/93/
