Calculator_all

About Calculator_all Android App

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

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' )
