LINEAR ALGEBRA PLUS CALCULATOR (matrix, equations)
LINEAR ALGEBRA PLUS is surprinsingly intuitive and easytouse.Videos containing examples of all its capabilitiesareavailable onthe website below. In them, you can see how fastandeasy to manageit is. A medium or long press on the solutionisenough to show thesteps followed to solve the exercise. Itallowsyou to save allcalculations in a LaTex file so that it canbeturned into a pdfdocument. WITHOUT ADVERTISEMENTS MATRICES: Up to8matrices, withup to 10 rows and columns, can be stored invariablesA, B, ...X,and then used in further calculus. Theprogramme cancalculate thedeterminant, rank and inverse of eachmatrix. Complexmatrixexpressions (A*(B^(-1)-3A) can be easilysolved, and all thestepsare shown. It evaluates the determinant,rank and inverseofmatrices with one parameter. It also obtainslowertriangularmatrice, even with a parameter, displaying the stepsofthe Gaussand Gauss-Jordan method. It also calculatesthecharacteristicpolynomial, eigenvalues and eigenvectorsofendomorphisms andchange of basis matrices P y P^(-1).LINEARSYSTEMS OF EQUATIONS:It classifies and solves Dependent/Independent Consistent Systemsor Inconsistent Systems of up to10equations, even with oneparameter. It also shows the steps tosolvethe system (Gauss'Method, Inverse Matrix Method and Cramer'sRule).POLYNOMIALS: Upto 8 polynomials (max grade = 9), can bestored invariables A, B,...P and then used in differentpolynomialexpressions. Itfactorises and calculates rational andreal rootosof polynomials .Polynomial divisions are possible (allthe stepsare given).Complex expressions can be easily solved(p^3*(2p-q^2)),whichmakes it easy to solve a great variety ofequations. It showsallthe steps necessary to factor a polynomialwithout more thanmakinga long click on the solution. 3D GEOMETRY:This module allowsyouto enter points, vectors, straight lines andplanes, andthencalculate new ones dependent on the first ones("linewhichcontains a point and is perpendicular to aplane","pointsymmetrical about a straight line" ... ) or makecalculuswith them(intersections, distances, relative positions,angles,change ofbasis ...). By making a long press on the screen,it showsall thenecessary steps to obtain the solutions (by variousmethodswhenpossible). 2D GEOMETRY: This module allows you toenterpoints,vectors and straight lines, and then calculate newonesdependenton the first ones ("line which contains a pointandisperpendicular to another line", "point symmetrical aboutastraightline" ... ) or make calculus with them(intersections,distances,relative positions, angles, change ofbasis ...).

Scientific Calculator 3 1.8
Scientific Calculator 3 is an easy to useuniversalscientificcalculator app for smartphones, tablets orotherAndroidtouchscreen devices. It evaluates mathematicalexpressionsunderconsideration of the algebraic convention "bracketsbeforepowerbefore point before line calculation". The rounding ofresultsisadjustable between 5 and 15 digits. Available notationsarenormalnotation (NORM), scientific notation (SCI) andengineeringnotation(ENG). Trigonometric calculations optionally inDegrees(DEG:1°=PI/180) or Radians (RAD: 1rad=180°/PI).ScientificCalculator 3provides a large history display, where allinputs andresults canbe checked easily.
