It's also capable of exchanging spreadsheet data, formats, pivot tables, and other information typically included in a spreadsheet. OpenDocument can exchange spreadsheet formulae (formulae that are recalculated in the spreadsheet); formulae are exchanged as values of the attribute table: formula.
Equation Editor Equation Editor allows for mathematical equations to be included in Excel, Word and PowerPoint. Mathematical symbols appear in a toolbar at the top of the screen and the user can combine these along with numbers and/or variables to create complex equations and mathematical statements.

Taking the natural logarithm of the former equation gives: = () When plotted in the manner described above, the value of the y-intercept (at x = 1 / T = 0 {\displaystyle x=1/T=0} ) will correspond to ln ( A ) {\displaystyle \ln(A)} , and the slope of the line will be equal to − E a / R {\displaystyle -E_{\text{a}}/R} .
Excel offers many user interface tweaks over the earliest electronic spreadsheets; however, the essence remains the same as in the original spreadsheet software, VisiCalc: the program displays cells organized in rows and columns, and each cell may contain data or a formula, with relative or absolute references to other cells.
Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated.
Pivot tables are not created automatically. For example, in Microsoft Excel one must first select the entire data in the original table and then go to the Insert tab and select "Pivot Table" (or "Pivot Chart"). The user then has the option of either inserting the pivot table into an existing sheet or creating a new sheet to house the pivot table.
A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.
Linear interpolation on a data set (red points) consists of pieces of linear interpolants (blue lines). Linear interpolation on a set of data points (x 0, y 0), (x 1, y 1), ..., (x n, y n) is defined as piecewise linear, resulting from the concatenation of linear segment interpolants between each pair of data points.
