Webassign Calculus 1 "Optimization Tricks"

 AKA, how to "cheat" efficiently and gratuitously, particularly necessary if you're trying to do the whole thing in the free trial period.

Red numbers in Webassign mean they change them to make it harder to cheat. They also haven't changed this mechanism for 10 years, so most if not all of the possibilities have already been answered. Google the text of the problem, and put quotes around the red variables to guarantee you get the results. This is a very efficient way to complete classically slow word problems (One red number is a guaranteed copy-paste solution, two is iffy, three is unlikely. But try anyway, since that could be free credit). If you don't, then it becomes a slower, but not particularly slow, replace-the-numbers problem.

There's actually quite a few ways to create simple replace-the-numbers situations:

If you hit "Watch it", you can get a solution to a similar problem. 

If you hit "Read it", and go to the examples section, one can avoid the unreadable prose for the most part, and force the book to actually tell you how to solve the problem. (Although frequently this doesn't work if there isn't a close enough example.)

If you hit "Practice Another", get it wrong, and ask what the solution is, you can get for free the work to, again, a similar problem. I don't know if the teacher is made aware of you doing this, so it's your risk. (Whether that matters, or he even checks if it does, I do not know.)

Limit problems can typically be countered with Desmos.com, and a good (by this, I mean either extremely close or far) 

Use more tools and sorts of tools, rather than fewer. Specific ones have weaknesses that hamper or prevent efficient problem-solving. Desmos makes short work of infinite limits, Mathway can't. Derivative calculator actually gives you work, and Mathway "can't". 

Master your tools. Learn about all of the ways to enter problems, how to take little shortcuts, if there's any time to pay attention it's most certainly in learning how to solve everything with the calculus calculator. FAR better time-investment, if you are going to pick one, than straightforward notelearning.

And naturally, good effort in class is probably just as useful generally. This gives you more context for the answers that the machine spits out, and a chance to fix an answer that doesn't bother making sense to Webassign.

Don't bother too much with overly difficult (or uncheatable) ones; just move on. Better to spend 20% of the effort to get 80% of the credit, than 80% more effort for 20% more credit.

If you are paranoid, do none of this. If you believe our institutions are incompetent, and really just copy-paste whatever number's on the webassign without checking (and that's closer to the truth), then do what you like, really. But I'm the CIA handing out the Kalashnikovs, and you're the afghans with political agendas. It's still your responsibility to not get killed.

The paranoid cheat-lover may find it useful to setup a professorial account beforehand, and inspect how his methods show up to the professor. Easy or not, it's a way to do it.

Thanks for your time. You won't get an easy solution from me (since that's kind of pointless), but I'll tell you how to get the solutions yourself. Ever heard, teach a man to fish, he'll need no further handouts? And you'll never need another answer sheet again. Although that's a valid way of getting solutions.
