Working with a database in MS Excel
The file MS Excel on a sheet "Database" to build a simple database with 50 records with fields.Format the field according to the type of data contained in these fields (text, date, number, money ...)
Number of order
|
Account number
|
Provider
|
Delivery Date
|
Goods
|
Price
| Quantity |
Cost
|
The numbers from 1 to 50
|
Several numbers from 84123 in increments of 7 to increasing
|
Make a choice from a list of providers:
1. Delicious products
2. Builder
3. Epicenter
4. Household goods
5. Gardener
|
Several dates from now to the past with step 8 days
|
Enter one of 10 available products:
1. Meat
2. Milk
3. Brick
4. Cement
5. Rake
6. Hose
7. Dishes
8. Kettle
9. humus
10. Fertilizers
|
Arbitrary numbers for each product
|
Several numbers from 227 in steps towards increasing 9
|
The formula of price (quantity multiplied by price)
|
Run the task of working with the database. The results obtained during the database to insert a new page file.
1. To select vendor records "Gardener" with the product number is more than 400.
2. To select entries supplies Dishes in the past two months.
3. Sort database suppliers simultaneously, and then the goods.
4. Find up the goods on the field "Quantity".
5. Create summary table, placed in areas of the diagram fields:
a. Page - "Delivery Date".
b. Column - "Supplier".
c. The line - "Goods".
d. Data - "Number"
Output data providers from provider "Epicenter".
6. Split database window between the cap and the table data (fixed area).

Plot a graph
Roses (curves Guido Grandi)
ρ=a*sin(k*φ), a and k - steel number (consisting of rose petals k for k odd and 2k for k even)
k = 2 (four-Rose), φ is [0,2π]
ρ=a*sin(k*φ), a and k - steel number (consisting of rose petals k for k odd and 2k for k even)
k = 2 (four-Rose), φ is [0,2π]

Plot a graph
Consider plotting in polar coordinates.
Archimedean spiral
ρ = aφ, a> 0
1. Let a = 2. In column A, we insert the angle φ on the interval [0,2π] in increments of 0.25.
2. In Column C enter the appropriate formula Archimedean spiral.
3. Convert polar coordinates into Cartesian using corresponding formulas connection between these coordinates.
The relationship between Cartesian and polar coordinates:
x=ρ*cos(φ)
y=ρ*sin(φ)
Archimedean spiral
ρ = aφ, a> 0
1. Let a = 2. In column A, we insert the angle φ on the interval [0,2π] in increments of 0.25.
2. In Column C enter the appropriate formula Archimedean spiral.
3. Convert polar coordinates into Cartesian using corresponding formulas connection between these coordinates.
The relationship between Cartesian and polar coordinates:
x=ρ*cos(φ)
y=ρ*sin(φ)
4) Building a spot-chart based column D i E.
