Calculator-all is a small scientific and syntactic calculator which allow yu to compute and draw différents functions type easily! Calculator-all is very simple to use and have almost usuals functions on one screen Calculator-all include a simple calculator, a graphic drawer and a Matrix computer(ex: +,-,*,/ ,transpose, triangularisation..). if you have some problems please read 'How to use'
usuals functions: log(): decimal logarithm ln(): neperian logarithm e^(): exponential, eleur value sqrt(): sqrt fact(): factorial (also use '!') a^b: power sin(): sine cos(): cosine tan(): tangent asin(): Reciprocal Sine acos(): Reciprocal Cosine atan(): Reciprocal tangent snh(): hyperbolic sinus csh(): hyperbolic cosinus tgh(): hyperbolic tangent abs(): absolute value dgr(): a degree value(press d) rad(): radian value (press'r') C[a;b]: combination ex: C[2;4]=6 A[a;b]: Arrengement ex: A[2;4]=12 B(): Convert decimel to binary D(): convert binary to decimal tr(): Matrix transpose tgl(): Matrix triangularisation det(): Matrix determinant fract(): get irreductible fraction (LongClik on ')') ans: the last result rnd: a randum number *More: %v=val initialize variable v = val Gauss([M1];[M2]) resolve equations systems expl:Gauss([1,2;3,4];[1;3]) read how to use(all equations types) Kutta(y'(t);step;inf;sup;y(0);acc) resolve differentials equations with Range Kutta Method expl: Kutta(2y-2t;0.1;0.2;0.5;0.6;3) read how to use root to have polynomial roots ex: 3x^2+x-2=0 just write root[3;1;-2] more informations please read how to use
NB1: when you start calculator-all, to have Menu Items, just press Android natural options button (important)
NB2: acos, atan,asin can be writed with Android Keyboard or Calculator-all keyboard.(first time press button 'a',second time, press the function. ex:'a'>'sin' )

at the beginning, I have make this soft for my own school's use but now it is your Made by the TtjSoft.....(Toukea) contact: email@example.com, dn't hésitate!
