Deret Geometri : Scored Geometry and Geometric Series Addition Results

Geometric series can be written as follows :

          a + ar² + ....... + ar^n-1

            a : tribe initial

          r : ratio

          n : a lot of tribes

For the number of runs formula n geometry like this:

Deret Aritmatika: Program Seeking Series Arithmetic and Number Series Arithmetic

Arithmetic series in the field of mathematics is the sequence number in which the next number of additions to the previous number by a number of specific differences. Examples are 3,5,7,9,11,13, ..... Arithmetic series can be expressed with the following formula:

Searching (Array One Dimension) : Finding a Number From Several Numbers

Still talking one-dimensional array problem. In the array much to do kit. From the most minor sort the numbers to the greatest or from greatest to smallest. Also we will discuss this time is to find a number of the many numbers entered.

For example there is input data 5, 6, 2, 4, 8. 5 will automatically be stored in the array index of 1, 6 will be stored in the array index 2, 2 will be stored in the array index of 3, 4 will be stored in the array index 4, 8 will be stored in the array index 5,

Join The Set: The Multiplication On The Set

This time we will discuss the multiplication on the set or the more frequently heard hipunan join. Multiple purpose here is not like multiplying 2 x 3 = 5, but we are combining two or more sets.

For example we have set A and B, A × B means the set of all ordered pairs with the first element of each pair selected from A and the second element selected from B.

Example:

Matrix Symmetry: Program to Check a Matrix Symmetry

This time I will discuss about the matrix symmetry.

Box matrix A is called symmetric if A = A^T
Examples of symmetric matrices:
