There are three standard ways of traversing a binary tree T with Root R. These three algorithms, called Pre-order , Inorder and post order. Below is the example of those algorithm:

### BB101 : FINDING THE RESULTANT OF NUMBERS OF FORCES

Adding 2 forces are quite a simple things, but this simple thing is also can be use to determine the resultant of numbers of forces acting on a point. Those forces known as the polygon of forces because we can redraw the forces as a polygon. Here is an example how to calculate the resultant and direction involving the process of resolving and resulting.

### BA202: Spanning Tree...its a game!!

find the spanning tree |

Most student didn't aware that they actually know the concept of spanning tree before. Its called the Maze game...finding a path in a puzzle maze. Yes, it is exactly the same thing with what we call spanning tree..here just try to find the path...should you able to seek it??

### BB101: Adding Forces as Vectors

**How to add two forces acting onto a point but in a different direction and plane?**

As we know that forces are vector, so we cannot adding or subtracting them like the scalar magnitude, therefore we have to use the triangle law or parallelogram law to determine the resultant. Please watch the video below to enhance your knowledge.(This video is a copyright of Lucid Education)

### BA202 : DOES INFINITY COUNTABLE?

Dear student,

Our last class we do a lot of discussion on a set of Numbers. All numbers are

In other hand, decimal number cannot be listed......even you try to list a decimal number from 0 to 1, therefore, we call that decimal numbers are

Our last class we do a lot of discussion on a set of Numbers. All numbers are

**infinity**...such as the Positive Integer I = {1,2,3,4....} and so with the Natural number N= {0,1,2,3....}. But both Integer and Natural Number can be listed so we call it the**countable infinity**.In other hand, decimal number cannot be listed......even you try to list a decimal number from 0 to 1, therefore, we call that decimal numbers are

**uncountable infinity.**So did you get the idea? try to find another set of number which can be classify as uncountable infinity....## Monday, January 14, 2013
