I have three columns that equal a sum column. I now want to take the sum column and find out what 3.33 percent will be. This is a commission.


=SUM(A1,B1,C1)*3.33% or =SUM(A1,B1,C1)*.0333
(A1, B1, C1 are the cells that contain the sum of the individual columns.
=SUMCOLUMN * 3.33% (enter the cell of the sum for the three columns) = C24*3.33%

3.33% =0.033
=CELL * 0.0333
=CELL * 3.33%

Only one button which is used for integration/differentiation is not responding


I am not sure what you mean. The key allows yous to calculate the definite integral of function which you enter on the command line. You must also enter the lower and upper limits. When used do differentiate, you must enter the function, and specify the point at which the first derivative is evaluated. Try the two features with simple functions to test whether the calculator is working.

Can the casio fx9750gplus calculator show differentiation/integration etc. for example differentiate 5x^3 and have it show 15x^2?


Sorry to disappoint you but the Casio FX-9750Gplus does not handle symbolic calculations. It does not have a Computer Algebra System or CAS. It can however calculate the numerical integration of a function between two limits, as well as the first and second derivatives of a function at a given point.

  1. To access the numerical integration and differentiation,
  2. Press the Menu button.
  3. Highlight the RUN icon and press [ENTER/EXE]
  4. Press [OPTN][F4:CALC]. Then
  • Press [F2:d/dx] for first derivative
  • Press [F3:d^2/dx^2 for second derivative,
  • or [F4:integral]

Differentiating and Integrating Problems


Hello,
This means that you are using a non-algebraic variable in an expression. I know, I am not even paraphrasing. Exemple: if you write 2 + johnQ, where johnQ is a table of data, a picture or a GDB, graphical data base object.

8d787a6.jpg Here is an exemple where mat is a 2X2 matrix and mot is a table.
Hope it helps.

How to do profit and loss a/c in ms excel


Hi saleem_share,
I'm not sure why you would want to use excel to create a P&L, but the same formula would apply to excel as it would for a standard P&L. In one section of the spreadsheet add all of your income accounts. Then Subtract your cost of sales from that. That would equal your Gross Profit. After that add all the rest of your Expenses, and subtract from the Gross Profit, which would give you your net Profit or Loss Example:
Description
Amount
Formula
Sales Product A
1,000.00

Sales Product B
1,000.00

Total Sales
2,000.00
SUM(C1:C2)
Cost of Sales Product A
500.00

Cost of Sales Product B
200.00

Total Cost of Sales
700.00
SUM(C5:C6)
Gross Profit
1,300.00
SUM(C4-C7)



Auto
25.00

Utilities
50.00

Payroll
300.00

Office Supplies
20.00

Total Expenses
395.00

Net Profit
905.00
SUM(C8-C14)


I hope this helps
