In order to deal with the modulus sign, we must take account of 2 possible cases:

Case 1: |2x + 1| = (2x +1). In this case we can solve algebraicly, preserving the inequality sign, to get...

To solve this problem, we must first differentiate:

Identify that we are able to use the product rule as our expression is of the form y = f(x)g(x) where f(x) = e^(2- x) and g(x) = ln(3x-...

most people are immediately confused when they see a surd or a fraction because they find it hard to apply the rule of integration directly to them. however it is not as complicated as it looks. all th...

Well, you need to have a clear mind and know well the pattern that they will gonna ask. Then all you have to do is make sure you understand all the skills that you required to need.

This is an example of a linear equation. 
To find x we can apply the same operations to both sides in order to isolate x.
First we can subtract 6 from both sides.
This gives us 4x on the le...
