Chapter 2 / Little questions about quiz coverage
« on: September 22, 2020, 05:33:15 PM »
I noticed that on qurcus, it said that the quiz would be one problem from Home Assignments to Week 2. But by the email from the professor, the Bernoulli function is covered in the quiz, but the home assignment for Bernoulli function is actually not in week 2. So do I need to finish doing problems to section 2.4 to prepare for the quiz?

For this question, I need to get an interval where the solution is defined. However, for the interval of x, I got x>=sqrt(15)/2 or x<=-sqrt(15)/2, but the answer only has x>sqrt(15)/2. I don't know why. Could anyone help me?
