Starting off, within the concept of mathematical induction, there are two major steps. The first is "Show true for n=1" and the second is "Assume the statement is true for n=k, and prove true for k+1." 

Using such steps in an example...

If the equation or problem given is 1 + 2 + 3 +4... + (2n-1) = n^2 , one would first begin by proving that n=1. To do this, you would plug in a "1" for anywhere you see a "n" within the equation. Therefore it would look 2(1) - 1, which is equal to 1 - and then (1)^2, which is also equal to one. By doing that, we have proved that both the left hand side and right hand side are equal to 1, showing true that n=1.

After that, we would continue on to step 2, which is "assume the statement is true for n=k, and prove true for k+1." This means that first, we will plug in a "k" for anywhere we see a "n" in the problem. Upon doing so, the resulting equation would be:

 1 + 2 + 3 +4... + (2k-1) = k^2  (This is known as the recursive formula)

After you find the equation above, you then plus in a "k+1" for anywhere a k is present. Therefore, the next resulting equation would be:

 1 + 2 + 3 +4... + [2(k+1)-1] = (k+1)^2

You then simplify the equation and plug in the recursive formula (mentioned above). This indicates that the equation will become:

k^2 + 2k +2-1 = (k+1)^2

and then simplifying it down

k^2 +2k + 1 = (k+1)^2

which is

(k+1)^2 = (k+1)^2

Thus we have shown that k+1 is true. It follows from Mathematical Induction that the statement is true for every positive integer.

Moving along, in class, we did a project called "The Tower of Hanoi." This particular project was to find the correlation between the number of rings and the amount of times it was moved. Starting with 2, then 3, then 4, and then maxing at 7 rings, with three poles; my group discovered that the equation for the correlation was:

T1 = 2^n - 1

and the recursive of it was:

Tn = 2Tn +1

An observation i concluded while experimenting with the discs is that if you move the lowest number to the second pole, and then move the second lowest number to the third pole, you can then put the one on the second pole on the third pole - therefore, giving room for the third to be moved to the second pole. By using such a strategy, it is easier to move all the discs from the first pole to the third pole.

Greetings, dear guests of Mathland!~

Today I will be expanding on sequences and series. For sequences and series, there are two types:
-arithemetic
and
-geometric

For the arithemetic sequence, the formula used is an=a1 +(n-1)d. "D" is the ratio between each number - otherwise known as the common difference.
For the geometric sequence ,the formula used is an=r^(n-1)
In addition to using these equations, one is frequently asked to find the sum of the series, meaning what is the sum of the pattern added up to a specific number. To find the number, summation notation is used.
The arithmetic formula for this is Sn = n[ (a1+an)/2 ]
The geometric formula for this is Sn = [a1(1-r^n)]/1-r
Here is an example:

That is all for today! Good bye!~

Salutations, fellow visitors of Mathland!

How have you all been? 

Good I hope.~

I must tell you, but I have just learned about the most fascinating piece of knowledge.  It has compelled me so much that I must share it with you all.

This fascinating thing is known as "graphing systems of inequalities".

Let us start, yes?~

In the beginning of this lesson, we must review the three equations of the three different graphs:

Line: y=mx + b

Parabola: y = (x-h)^2 + k

Circle: x^2 + y^2 = r^2

Here are the steps to graphing the equations:

1) Determine which graph is used and graph each equation.

2) Pick a test point that is not on the line.

3) Shade the plane containing the test point if the test point satisfies the equation. Shade the other plane if it does not.

Also make sure to pay attention to the signs. 

If the sign is greater or less than and equal to then the graphed line is solid. 

If the sign is only greater than or less than, then the graphed line is dashed.

Below is an example:

Well, that is all for now! See you next time.~

Goodbye.~
