Hello Pipioluu!!!

Last art class, was abaut maths (HORROR!!!) abaut impossible figures, it strange figures have a trick to do:

(Escher two)

-All the lines have to be 30º. It's more easy that you think. We have right triangle and a set square:
    (Right triangle)     (Set square)

How to make paralel lines

It's in catalan but I'm going to translate:

1. Fit the right triangle to the top.

2. Put the set square next to the right triangle, like in the photography.

3. Grab the right triangle and muve up or down the set square

Good week

LA ESPONJA DE MENGER

Alguien había escucha alguna vez hablar sobre la esponja de Menger?

La esponja de Menger es un fractal en forma de cuba.Se descrivió por primera vez en el 1926, por Karl Menger mientra exploraba el concepto de dimensió topológica2

La esponja tiene una superficie infinita y al mismo tiempo encierra su volumen es cero.

La construcción de la esponja de Menger se define de forma recursiva:

1-Comenzamos con un cubo.(primera imagen).

2-Dividimos cada cara del cubo en 9 cuadrados. Este se subdivide en 27 cuadrados más pequeños, como le sucede al cubo de Rubik.

3-Eliminamos los cubos centrales de cada cara (6) y el cubo central (1), dejando solamente 20 cubos (segunda imagen).

4-Repetimos el prceso 1, 2 y 3 para uno cada uno de los 20 cubos menores.

Y este es uno de los muchos fracteles que se conocen hoy en día (más adelante os explicaré otros fracteales).

Hello  how are you today I gona show you how to do a root.

Adding radicals should be similar, that is, they must have the same index and the same radicand.

Coefficients join and leave the same index and the same radicand.

When there are similar factors to be drawn before the radicand because they are:

Hi I want to show you a little part of what is tne number pi Π

Π (pi) is the relationship between the length of a circumference and its diameter, in Euclidean geometry. It is an irrational number and one of the most important mathematical constants. It is often used in mathematics, physics and engineering. The numerical value of π, truncated to its first numbers, is as follows:

 3,14159265358979323846
The value of π has been obtained with various approximations throughout history, being one of the mathematical constants that appears more in the equations of physics, together with the number e. It should be noted that the quotient between the length of any circumference and that of its diameter is not constant in non-Euclidean geometries.

Encara que no ho sembli molts vidiojocs de matar o coches es necessita fer algunes equacions. Ex.

Un enemic esta 62m. , en el teu franco pots marcar tres distàncies:
-50m.
-150m.
-300m.

Desprè necessites calcular la velocitat que va aquell home (x) i si has fet l'equaci bé haries d'haver matat
l'enemic.

En el cas d'un coche seria així:
El teu coche va a (x) Km./h la curva esta a 50m.  cap a l'eaquerra i fa un vent de 3Km./h dirrccio oest. A quina velocitat a d'enar el coche per agafar la curva i no estrellarse?
Ara l'únic que heu de fer es una equacio molt simple.

Hi guys today I will sow you a successio of numbers  

I will tell you what is andt were can you find it

The Successió Fibonacci invented Pissano Leonardo.

It is an infinite number Successió natural works, as follows:

1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 , 55 , 89 , 144 , 233 , 377 , 610 , 987 , 1597

What we do is, we add one to one, that two, we add to this the second one, which would give 3 to this we add the second third, which gives 5.

In conclusion the only thing we are doing is adding a number before the number is, add the previous number, for example:

4+3=7      7+4=11 

Resultado de imagen Succession of Fibonacci immatge this can be seen as the conch, is becoming increasingly larger, since it will add more and more numbers.

In the laditori in bcn it has the soccecion of fibonacci in her roof but it’s with squares

look like the succecion of fibonacci

Hello Pipiolu!

It's me again :)
Do you know what is a MONOMI? And a POLINOMI?


A MONOMI it's an algebraic expression that have: Numeral part and Literal part. It have to has an index that has to be positive, not negative. If it have negative index, itsn't a MONOMI.

·Example of MONOMI: 21x2

And a POLINOMI are more than two MONOMIS (BINOMI).

·Example of POLINOMI:  5x6+11y4+38xy7

Now I lend you other mathematic photo:

ALMOST NINETY DEGREES

This summer the weather was hot. So we can see that in Barcelona (We can know that it's Barcelona because it is "La Sagrada Familia"), ALMOST NINETY DEGREES!!! How many agrees do you think the girl do?
