Description:

Problems involving absolute values are pretty common for IIT JEE exams. IIT aspirants must be familiar with the notion of absolute value and be fluent in applying varies technique for dealing with this type of problems. This test checks the ability to solve equations involving absolute values. Although almost all the problems could be solved using interval method, in many cases it is time consuming. Try to solve this test yourself. If you find that some of the equations are pretty difficult or time consuming, attend my public class to get advantages of varies technique that allow you to solve these problems effectively in a short period of time. Then try to complete test 2 with more complicated equations involving absolute values.
