M#Math works 100% offline, and in an 'expression-look-alike' style. ▣ user-file sharing by Bluetooth▣ e-mail user-files▣ user-file directory (file create and save)▣ tutorial directory with 60 tutorials▣ display commands and results ▣ thousand commas ($10,000,000) available▣ versatile keyboards αβγδεζηθικλμνξοπρστυφχψω ΓΘΛΞΥΦΨΩΔΣΠ Greek Characters ¹²³⁴⁵⁶⁷⁸⁹⁰·⁺⁻ superscripts ₁₂₃₄₅₆₇₈₉₀₊₋ subscripts °`⚑⚐ℹℯπ√∇∂∫→⇄⍷∅∞ℽēℕћҟℛℬℾ≤≥≠×÷Å ▣ sale and tax 100 -%20 +%10 ; // %20 sale, %10 tax 80 // 100 - 20 (minus %20) 88 // 80 + 8 (plus %10) ans = 88 ▣ feet and inches (ft'in'') 5'3'' ; // 5 feet 3 inches in meter ans = 1.6002 5' 3'' * 3' 0.25'' >>yd2 ; // area of plate in [yd²] ans = 1.76215 [yd²]▣ coupled nonlinear equations 3β = 2α+1, 4α³β + 5αβ³ = 4are solved starting from (α,β) = (1,1) by the following command solve .α.β {1,1} ( 3β = 2α+1, 4α³β + 5αβ³ = 4 ); to reach at one solutionans = [ 0.77734 ]₁ [ 0.85156 ]₂▣ Unit conversion is fast and convenient. For example, 80℉ Fahrenheit is all-in-one converted into 80f >> ; 26.6667 ℃ 80 F 539.67 R 299.817 K ans = 299.817▣ M#Math can be also considered to be a mini-C in that several keywords of C-language if else do for while break continue goto switch case default return void double are installed to work in M#Math. ▣ Built-in-App tutorials cover ● Unit Conversion ● File managing ● Equation Ax=b ● Line y=ax+b ● Parabola y= ax²+bx+c ● 3rd-order y= ax³+bx²+cx+d ● High-order and Circle ● Triangle ∆ABC ● M#Math as mini-C ● 2D Graph ● 3D Graph ● Complex Numbers ● Polynomial ● Sequence and Series ● Matrix ● Vertex ● Coordinate System ● Character and String ● Grammar of Function ● Integration ∫.x ● Differentiation ∂.x ● ∇φ, ∇•u, ∇✕u, ∇²φ ● Finding Roots ● Ordinary Differential Equation ● Initial Value Problem ● Boundary Value Problem ● Eigenvalue Problem ● Parabolic PDE ● Digital Signal Processing ● Mathematical Constants ● Physical Constants ● Properties ● Table of Characters ● Table of Laplace Transform ● Table of Fourier Transform
