PDFtk (short for PDF Toolkit) is a toolkit for manipulating Portable Document Format (PDF) documents. [ 3 ] [ 4 ] It runs on Linux , Windows and macOS . [ 5 ] It comes in three versions: PDFtk Server ( open-source command-line tool ), PDFtk Free ( freeware ) and PDFtk Pro ( proprietary paid ). [ 2 ]
Foxit PDF Reader (formerly Foxit Reader) is a multilingual freemium PDF (Portable Document Format) tool that can create, view, edit, digitally sign, and print PDF files. [3] Foxit Reader is developed by Fuzhou , China-based Foxit Software .
[1] Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.
These definitions E 1, E 2, and E 3 of the envelope may be different sets. Consider for instance the curve y = x 3 parametrised by γ : R → R 2 where γ( t ) = ( t , t 3 ) . The one-parameter family of curves will be given by the tangent lines to γ.
Thus, for example, the product of a 1 × n matrix and an n × 1 matrix, which is formally a 1 × 1 matrix, is often said to be a scalar. The real component of a quaternion is also called its scalar part. The term scalar matrix is used to denote a matrix of the form kI where k is a scalar and I is the identity matrix.

A numerical solution to the heat equation on a pump casing model using the finite element method.. Historically, applied mathematics consisted principally of applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variational methods, and numerical analysis); and applied probability.
