Ellipse Line Intersection

In this article we discuss ellipse line intersection. Ellipse is a conic section of geometry function. Ellipse can be defined in mathematically a plane passing through the right circular at angle between `0^o` to `90^o` . Ellipse can be included in two points like A1, A2. These two points called  focus.                                                     

                     

We are taking any two points on an above ellipse, the sum of the distance from the focus points is constant.

Shape of the ellipse line intersection:

The intersection of line in ellipse at centered origin. The line can passing through the points is `(x_o, y_o)` or origin. 

                           

The formula for ellipse is given below,
x^2/a^2+y^2/b^2=1`
where,
a=horizontal semi- axis
b=vertical semi-axis
 The trigonometry formula for ellipse is,
x=acos(t) and
y=asin(t)
where,
t =ellipse parameter
a=horizontal axis
b=vertical axis

Some important properties of ellipse line intersection:

• Center of ellipse :                 

It can be defined as connecting the focus points by using inside the single midpoint. It is also called as intersection of major and minor axes.                                             

• Major and Minor axes:

The longest diameter of the ellipse is called as major axes and shortest diameter of the ellipse is called as minor axes.                               

                    

• Tangent:

A line just touching one point on a ellipse is called as tangent.
                                             

                

• Secant :

The intersection of two points on an ellipse is called as secant.                                                            

                    

• Chord :

It can be defined as a line just linking any 2 points on ellipse. 

Triangle Online

A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC. In Euclidean geometry any three non-collinear points determine a unique triangle and a unique plane. (Source: Wikipedia)

Description to four sided polygon:

Let us see the brief discussing about the four sided polygons:
Square:
square has four equal sides. the following properties are used in square.



Area of the square :
A = a²
where a represents the length of one side.

Perimeter of the square :
P = 4a
where a is one side length value.
angle: all the angles are right angle (90^o)
Rectangle :
The opposite sides of the rectangle is equal.


Perimeter of the rectangle:
P = l+w+l+w
where l = length
and w = width
P= 2l+2w
    = 2(l+w)

Area of the rectangle :
Area A = length and width
         = lw.
opposite angles are congruent.
opposite sides are parallel.
Length of diagonal is calculated by
d= `sqrt (l^2+w^2)`

parallelogram:
Parallelogram has four sides, and the properties are listed below



Perimeter of the parallelogram
P = a+b+a+b
 = 2a+2b.

Area of parallelogram:
The are of the parallelogram is represented as
A = base * height
 = b*h
opposites sides are same length and also parallel.
opposite angles are congruent.

Rhombus:
rhombus is a quadrilateral which has four sides, the properties are listed below.


Perimeter of Rhombus:
P = a+a+a+a
 = 4a
where a is side length of the rhombus.
Area of Rhombus:
The are of the rhombus is calculated by

Triangular Prism Net

A triangular prism is a solid has two parallel faces which are congruent triangle at both ends. These faces form the bases of the prism

The others faces are in the shape of parallellogram.They are called lateral faces.
A right triangular prism that has its bases perpendicular to its lateral surfaces.

Once you've gone through these, take a look at our Volume of Rectangular Prism for more refernce.

Surface area of triangular prism=2base area+peripeter of base x height prism
Volume of triangular prism = Base area of prism x height of prism.

Under this concept of triangular prism we draw the triangular prism net.
 Prepare the model of triangular prism net ,we need a paper , a pencil or pen, a scissor and gum.

Method of preparing triangular prism net

 First we draw the rectangle and two triangles to two ends of the rectangle on the paper. Then cut out along solid sides.
 Fold along dotted lines.
 Use clear tape to fasten .
 If you want to draw or colour the net,do it before you tape it together.
 If you want to decorate it by gluing on decorations, tape it together first.

Quadrilateral Prism Shape

In geometry, an n-sided prism is a polyhedron made of an n-sided polygonal base, a translated copy, and n faces joining corresponding sides. Thus these joining faces are parallelograms. All cross-sections parallel to the base faces are the same (source-Wikipedia). If the prism has four sides then it is called quadrilateral prism. in this article we shall discus about some quadrilateral prism.

Quadrilateral prim shapes:

Formula for Volume of the cube V= a3 cubic units
Where,
            V = volume of the cube
 a =side length (or edge) of the cube.
Formula for surface area of the cube (A) = 6 a² square units

Rectangle prism:

It is one type of quadrilateral prism. The shape of the cube is shown in below.
Volume of rectangular solid (V) = length x width x height Cubic units
     = l x w x h cubic unit.
Total surface area of rectangular prism
                                    = 2 (length x breadth + breadth x width + length x height)
                                    =2(lb + bh+ lh) square units

Trapezoidal prism:

It is one type of quadrilateral prism.it has one set of parallel sides. The shape of the trapezoidal prism is shown in the figure.
Volume of trapezoidal prism = l x area of the base cubic units
                                                       l – Length of trapezoidal prism
                              Area of the base= 1/2 x (a + b) x h square units
                                                       a and b are length of parallel sides.

Volume of trapezoidal prism = 550 cm³

Figuring Volume of a Structure

Volume of structure
Volume is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape occupies. The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.
Volume is measured in "cubic" units.


Volume of Cylinder
A cylinder is a solid that has two parallel faces which are congruent circles. These faces form the bases of the cylinder. The cylinder has one curved surface. The height of the cylinder is the perpendicular distance between the two bases.
The volume of a cylinder is given by the formula:
Volume = Area of base × height

V =   r²h where r = radius of cylinder and h is the height or length of cylinder.

Volume of hollow cylinder

Volume of hollow cylinder
V=πR²h-πr²h
Where R is the radius of the outer surface and r is the radius of the inner surface.

Volume of Cone

A cone is a solid with a circular base. It has a curved surface which tapers (i.e. decreases in size) to a vertex at the top. The height of the cone is the perpendicular distance from the base to the vertex.

Volume of cone = 1/3 Area of base × height
V = 1/3πr²h where r is the radius of the base and h is the height of the prism.

Volume of Pyramid

A pyramid is a solid with a polygonal base and several triangular lateral faces. The pyramid is named after the shape of its base. For example, rectangular pyramid, triangular pyramid.
The lateral faces meet at a common vertex. The height of the pyramid is the perpendicular distance from the base to the vertex.

The volume of a pyramid is given by the formula:

Volume of pyramid =  1/3Area of base × height

V = 1/3Axh where A is the area of the base and h is the height of the pyramid.

a = 7
b = 5
c = 3

Now applying the formula,


= `(-5 +- sqrt(5^2 - 4 xx 7 xx 3))/(2 xx 7)`
=`(-5+-(sqrt(25-84)))/(2xx7)`
=`(-5 +-(sqrt(-59)))/(14)`
=`(-5+- i 7.68)/14`
=2.68 `+-i` -7.68
