I think it is helpful to let students know that you are looking for their thinking while problem-solving, and not just answers. Then you can ask questions like: Find all of the points on a circle of radius $8$ that have a slope of $\frac{3}{4}$. so that they can explain their problem-solving. Even if they do end up using advanced calculators, they will ...

Some of Chegg's competitors are Studyblue, Course Hero, Slader, and Cramster. However, Chegg is the market leader by a mile. It's a little difficult to sort out which of these businesses actually sell solutions, because they don't admit they do that. For example, the NY Times did a softball interview recently with Chegg's CEO, where they asked, "Many ...

If you are teaching algebra or calculus courses, Mathway and Symbolab have algorithms that allow paying users to see full solutions with steps shown. The algorithms often do strange things that no human would do, which allows you to catch students who use them. For example I gave the following question: Use the comparison test to show that this series ...

Note: It's possible that in the future, Wolfram Alpha will improve and be able to answer the questions in this answer, so it's best to actually try them in Wolfram Alpha first. Use questions that involve conditional statements and generic expressions. For example: If $\lim_{x\to\infty} f(x)=1$, then what is $\lim_{x\to\infty}\frac{f(x)}{x}$ equal to? ...

Not organised sites like Chegg but I try to keep an eye on several sources. Freelance "teachers" who solve exercises, sometimes somehow disguised as classes - classes where your exercises are solved. They can be found by Googling the name of the subject and "exams", the name of the institution or the exercise. It's easier in languages ...

one that hasn't been mentioned is Slader. I only learned about it through this article on cheating in a Princeton math course: https://www.dailyprincetonian.com/article/2020/05/princeton-teaching-assistant-math-department-slader-mat202-academic-integrity-cheating-covid

How were the "cheggspert" (i.e. the person employed by chegg to solve students' exam questions) and my student able to locate the github repository containing this question? Here's a possible timeline: A student posts the question to Chegg. The Cheggster, who probably keeps a trove of solutions to real analysis problems, digs up the solution and sells ...

Related rate word problem question with some geometry needed as part of the problem. But. I would caution you that if you are teaching weaker students, there is a problem in assigning tough problems in that you don't well evaluate their ability in basic methods. I would instead suggest alternatives like short duration (fixed time) remote exams. Also ...
