If you are someone who likes mathematics it will be useful for you to know that Excel has a lot of trigonometric functions, and we can use them whenever is necessary to plot your sinusoids. These are the functions of SIN (sine), COS (cosine), TAN (tangent), COT (cotangent), and there are many others as well. If you are curious you can easily find them in the Excel function library. How to draw a sinusoid?
Rounding functions are approximating numbers to higher or lower values. On that occasion, they are guided by mathematical principles. However, when pricing is often required, rounding is done at a higher or lower level according to a given degree of significance, which is the decimal number in relation to which the rounding is done. Dear merchants (and everyone else), we present you functions FLOOR and CEILING!
In one of the previous “recipes” you could find out how to calculate the number of past days between two dates. Excel has another function that can be used for this purpose. It is a hidden DATEDIF function, which, for two given dates, can calculate the number of years, months or days. The following text will be about how this function is used …
The search of data ranges is most often done with the help of LOOKUP functions, where we enter the criteria value, the search range (table) and the column containing the result values. After entering the formula, Excel finds and displays the requested value. There are several more ways to search the ranges when it is done relative to their position, which will be discussed more in the text that follows …
Depreciation means the expense of fixed assets. The depreciation calculation is used to find out how this cost should be spread over several periods, since it is assumed that we are not rich enough to immediately reimburse the cost of purchasing a fixed asset. Depending on whether we want to distribute the costs evenly or if we want to pay more in a certain period, in order to pay less, there are several functions for calculating depreciation.
