Identify the Parts of a Function Formula

A function formula has three components: – the equal sign – a function name – an argument

The argument is a value, cell reference, range, or text that acts as an operand in a function formula.

Example:

=SUM (E4:E22)

Solving Mathematical Problems

Mathematical and trigonometric functions are particularly useful for determining values such as: – Logarithms– Factorials– Sines– Cosines– Tangents– Absolute values

See Table 5-1 in student book,

Solving Financial Problems

Financial functions are used to analyze loans and investments:– Value of a series of equal payments – Present value of an investment– Payments required to repay a loan

See Table 5-3 in student book,

Inserting Times and Dates

Date and time functions may be used to – Convert serial numbers to a month, a day, or a

year – Insert the current date or current time.

See Table 6-4 in student book,

Time, date, and text functions

Using Logical Function Formulas

Logical functions, such as the IF function, may be used to display text or values if certain conditions exist.

For example the IF function will determine whether a student has passed or failed a course. The function formula IF(C4>60,“PASS”,“FAIL”) will display “PASS” if the value in C4 is greater than 60 and “FAIL” if the value in C4 is not greater than 60.

Summary

Function formulas are special formulas that do not require operators.

Excel has more than 300 function formulas. Function formulas may be used to perform

mathematical, statistical, financial, and logical operations.

Function formulas may also be used to format text and insert dates and times.
