To really master a subject you must be able to analyze data and make sense of it, an analytical function worksheet is an answer to this problem. With this type of worksheet the answer to all questions in any equation or calculation is available and it is easy to follow with a variety of chart types. This is a must for almost any course to be taught to a student, so these function worksheets are used extensively.
Before answering a question on a function worksheet it is necessary to determine the variable or variables that the question pertains to. Then decide how you are going to represent these variables in the chart types that you choose. These functions are often called autoregression charts or functions of the form x+y=z.
A chart is a representation of some series of data that has been input into a database for use in a question that might be asked. It is usually an image or graph that is created from the data entered into the question. As you answer the question you will enter the data in order to see the results, if you want to know more you can continue to enter more data and the curve will continue to change as you add to it.
Answers can come in the form of question marks, no answer and yes answer or the other way around. The function worksheet should always be the first chart that appears. When you do not have an answer, you must enter a question mark so that you are not required to enter an answer. The points in between the points are optional or data that you might enter in your own.
If you want to make sense of your data you should enter the answers for each question first on the function worksheet. The next step is to make sure that the values change from left to right. When you answer the question and then find that the values do not change from left to right you will need to convert it from an excel cell to a numeric value. By the time that you have to change the answers in the curve you have entered in the function worksheet you are likely to have forgotten one or more of the answers so you will have to start all over again.
The idea is to complete all the values to get a new value to fill the point that was left empty. If you cannot find the answer, you can use an Excel conversion number. This number is a combination of the previous answer and the current answer.
By using an autoregression chart with an answer as the curve you can come up with new answers for each question that comes up. It is very easy to go from the beginning of the line up to the end of the line up. It is also very easy to do the same thing with multiple curves.
If you would like to solve a problem in one answer first you should go back and use the function worksheet to obtain the previous and current answers, these can be converted to numeric values by using an Excel conversion number. By going back and forth with the functions of the function worksheet you can develop a good working knowledge of the functions of a curve. You will then be able to solve problems with different curves and answers.
