google.com /sheets. Google Sheets is a spreadsheet application and part of the free, web-based Google Docs Editors suite offered by Google. Google Sheets is available as a web application; a mobile app for: Android, iOS, and as a desktop application on Google's ChromeOS. The app is compatible with Microsoft Excel file formats. [5]
A workbook is physically represented by a file containing all the data for the book, the sheets, and the cells with the sheets. Worksheets are normally represented by tabs that flip between pages, each one containing one of the sheets, although Numbers changes this model significantly. Cells in a multi-sheet book add the sheet name to their ...
The values of the trigonometric functions of these angles θ,θ′{\displaystyle \theta ,\;\theta ^{\prime }}for specific angles α{\displaystyle \alpha }satisfy simple identities: either they are equal, or have opposite signs, or employ the complementary trigonometric function. These are also known as reduction formulae.
In mathematics, the Lambert W function, also called the omega function or product logarithm, [1] is a multivalued function, namely the branches of the converse relation of the function f(w) = wew, where w is any complex number and ew is the exponential function. The function is named after Johann Lambert, who considered a related problem in 1758.
Newton–Cotes formulas using points can be defined (for both classes) as 1 where. for a closed formula, , with , for an open formula, , with . The number h is called step size, are called weights. The weights can be computed as the integral of Lagrange basis polynomials. They depend only on and not on the function f.
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
The Bernoulli numbers as given by the Riemann zeta function. The Bernoulli numbers can be expressed in terms of the Riemann zeta function: B+n = −n ζ(1 − n) for n ≥ 1 . Here the argument of the zeta function is 0 or negative. As is zero for negative even integers (the trivial zeroes), if n>1 is odd, is zero.
In number theory, Ramanujan's sum, usually denoted cq (n), is a function of two positive integer variables q and n defined by the formula. where (a, q) = 1 means that a only takes on values coprime to q. Srinivasa Ramanujan mentioned the sums in a 1918 paper. [ 1 ]
