FIELD'S MEDAL

Hai friends. Today we are going to discuss about field's medal which is nothing but the highest award given in the field of mathematics. Everyone know that mathematicians doesn't have place in nobel prize. This is considered as Nobel prize of mathematicians and in contrast to it awarded it is awarded once in four years. It has another major restriction that the person need to be less than 40 years of age in 1st January  of that year.The monetary award is much lower than the 8,000,000 Swedish kronor (roughly 1,400,000 Canadian dollars).

It was started on the year of 1936 from then till now nearly 54 persons have been honored with this award. The last one was awarded in the year 2014.

Here comes the list of persons who got the medals with the places where they got and year.

SOLID GEOMETRY CONTINUES...

To be frank, I don't know how to define pyramid.

Parts of the Pyramid:

  • Base
  • Apex
Pyramid:

A pyramid is formed by connecting a base to an apex.

Actually Whenever we start with pyramid. All of us a sudden what we get in our mind is the Great pyramid of Egypt. But it is a type of pyramid.

We have different types of pyramid based on their bases. They are

  • Triangular Pyramid
  • Square Pyramid
  • Pentagonal Pyramid
In detail when taken in account, the following gives

Triangular Pyramid:

It has four faces in which three sides are triangles and the base is also a triangle  where four vertices with six edges are present also known as tetrahedron.

Square Pyramid:

It has five faces in which four side faces are triangles and base is a square where five vertices and eight edge are present.

Pentagonal Pyramid:

This has six faces in which five side faces are triangles and base is a pentagon where six vertices and ten edges are present.












Again they are divided into two types based on apex position. They are 
  • Right pyramid where the apex is straightly above the base.
  • Oblique Pyramid  where it is not straight.



And then again into two types based on their Bases. They are
  • Regular Pyramid when the base is a regular polygon.
  • Irregular Pyramid when the base is a irregular polygon.












This is  what I know about Pyramid. These images are taken from Google images.

SOLID GEOMETRY CONTINUES....

Next what we are going to see is Prism.

PRISM:

A prism is a solid object with identical ends, flat faces and the same cross section all along its length. Here cross section is nothing but a straight line cut across the object.

This cross section which is formed looks like a triangle. So it is known as triangular prism.

As it comes under the polyhedron, it has only flat surfaces and no curves. The parts of the prism were

  • Bases ( the ends of the prism were parallel and they are bases )
  • Sides ( the side faces of a prism were parallelograms and it has the property of a parallelogram)
There are six types of prism. They are
  • Square prism i.e cube.
  • cuboid i.e rectangular prism.
  • Triangular prism.
  • Pentagonal prism.
  • Hexagonal prism
  • Oblique Prism.



.


Again the prism are divided into two types based on their cross section. They are

  • Regular prism
  • Irregular prism
Whatever we have discussed above is all the examples of regular prism because they have regular cross-section and the cross-section are irregular in irregular prisms.

The next topic is nothing but Pyramids. We will see in later classes.






SOLID GEOMETRY CONTINUES....


When moving into the types, we had two types.  Now we will move onto the first one i.e Polyhedron.

Polyhedron as said before it must have flat surfaces. When moving into their types, we will start with cubes and cuboids.

Cube:

A cube is a polyhedron with six faces and all its faces are equal in length and breadth.

Properties:

  • It has 6 faces.
  • Each face will be having 4 edges looking like a square.
  • In total, it has 12 edges.
  • It has 8 vertices's i.e corners.
  • In each vertex 3 edges meet each other.
  • It also comes under the platonic solids.

As it  has six faces, it is known as hexahedron.

Example: simple dice we used to play ladder games.












 we will see formula's and about them in detail later.

CUBOID:

A cuboid is a box-shaped object which has different length, width and depth.

PROPERTIES:


  • It has six flat surfaces 
  • All angles are right angles.
  • All its face are in rectangles.
  • It also looks like prism because it has some cross-section along a length. 
  • Also a rectangular prism.
  • It becomes a square prism when two of its length become equal.

Example: Cardboard box, Pencil Box, bricks,...

Platonic Solid:

A platonic solid is also a 3-D shape in which each face is the same regular polygon and the same number of polygons meet at each vertex.

There are only five types of platonic solids. They are

  • Tetrahedron
  • cube
  • octahedron
  • dodecahedron
  • icosahedron

SOLID GEOMETRY

Solid geometry is the geometry of three dimensional figure. They are 3-D figures.The kind of space where we live in today.

They are called three dimensional because they have height, width and depth. While plane geometry has only height and width.

They can be divided into two types. They are
  • Polyhedra (They must have flat surfaces)
  • Non-Polyhedra ( They don't have any flat surfaces)
Polyhedra has four different types. They are
  • Cubes and cuboids
  • Platonic solids
  • Prisms 
  • Pyramids
Non-Polyhedra also has four different types. They are
  • Sphere
  • Torus 
  • Cone
  • Cylinder.
Solid have three properties. They are
  • Volume 
  • Surface Area
  • they have vertices, faces and edges.
Today we will start with vertices, faces and edges. 

Vertex and Vertices:

A vertex is a corner nothing but you people denote the points like A,B,C,D,..... The plural form is Vertices having more than one.

FACE AND FACES:

A face is an  individual surface like the one side of plane. Similarly plural form is faces.

EDGE AND EDGES:

An edge is an line segment joining two vertices nothing but the line between and b, c and d like that it goes on. As said above the plural form is Edges.


We will see them in later when we go deeply.

CIRCLE

Circle is also a two dimensional plane figure. The only difference is that it has no sides.

Circle is nothing but the set of all points that are in same distance from the centre.

Circle has three things in it. Now they are

  • Radius i.e distance from the center onward.
  • Diameter i.e it is a line drawn across the center in a circle.
  • Circumference i.e Distance once around the circle.
And in detail to define we have 
  • Diameter= 2*radius
  • Circumference=2*π*radius.

COMPOUND INTEREST


INTRODUCTION
  •  How many of you have been to bank with your parents?
  •  What have you observed in bank?
  • What is the main purpose of bank?
  • Why we need to deposit money in bank?   
  • We could also keep it in our home.Why the need?
  • What is the reason behind depositing money in bank ?



Simple interest:
When interest is paid only on the principle alone is known as simple interest.


formulas for simple interest

COMPOUND INTEREST:
The interest which is paid on the principle as well as on the accured interest is called as compound interest.





Explanation:

  • Consider vinay has borrowed Rs.50,000 from bank with 4% rate of interest for two years.
  • Vinay has to pay Rs.2000 as interest in the first year.
  • If he couldn’t pay it then the interest  will be added to the principle i.e. Sum = principle + interest
  • Sum = Rs.50000+ Rs.2000 = Rs.52000.
  • Now vinay has to pay interest in the second year with Rs.52000 as new principle.
  •  This way of calculating interest is known as compound interest.




Types of compound interest:




When compounded quarterly:



When compounded half-yearly:



When compounded annually:


Problem for example:





DIFFERENCE BETWEEN SI AND CI:




Real life applications:

These are some features which gives profit
      Provident fund
      Bank deposits
Negative features
      Credit card bills
      Loans

CONCLUSION:
