Software program is one powerful tool in which it has the capacity to create and manipulate such detailed information in the computer world. One of the software programs is Microsoft Excel, which is manufactured and developed by the Microsoft Corporation allowing the users to calculate, format and organize certain data through the formulas that uses one or more spreadsheet. Spreadsheet is a kind of application system that is broken up into rows and columns. Microsoft Excel is considered as organized information, which is based on different structures of operating systems, programs, utilities and applications enabling to work on the personal computer of every user. It is also considered as organized and written software by several computer programmers with its proper code and significant instructions in the varieties of the special languages within the computer’s software application.

Microsoft Excel is compatible with other software program applications, which are offered as product suites. The very first software program, which is similar with the Microsoft Excel, is the Multiplan. This was released in 1982. The software program application Microsoft Excel is considered the tool in spreadsheet or worksheet to perform data analysis, calculations and integrate information using any program. Having multiple spreadsheets or worksheets is called a Workbook wherein it has numbers of documented files, which are gathered and kept within the program files of the software application program.

In Microsoft Excel, ACOS function returns the inverse cosine or the arcosine of a single number. The arcosine is considered the angle which is the cosine of a definite number. The returned angle is measured in radians from the range of zero to Pi. The syntax for ACOS function in Microsoft Excel is ACOS(number). Number is considered as the cosine of an angle which the user wants to calculate, and then it must have a value of -1 up to 1.

Remarks:

Multiply it by 180/PI() or use the DEGREE function in Microsoft Excel if you want to convert the radians into degrees.

ACOS function in Microsoft Excel returns the Arcosine of one number or the radius value. Keep in mind that arcosine is considered as the inverse the Cosine function. Therefore, this is the angle, which has equivalent cosine to one given number.

Exercises of ACOS Function

  • Key in different numbers from -1 to 1 within a range of cell, from A1 to A6. In cell A7, enter this formula, “=ACOS(A3)” then retype the ACOS formula, “=ACOS(A1)”.
  • The user must have to work on the database right from the exercise one. Then use the Excel’s ACOS Function in “C4 = ACOS(A5)”. Then try to find out if what happens when you use ACOS in the empty cell such as “ = ACOS(F1)” or “ACOS(A20)”. Is it similar with the zero value from the above example?
  • Then try to use ACOS in the range of the different cells and then try to use the false range. Then type in the similar cell “=ACOS(A1:A2)”. Does it works? In addition, this is the only array option that the user may type to get the result instead of certain error and the “=ACOS(A1:A2)” returns alike such as “=ACOS(A1)”.
