Calc v0.11a pre-alpha version
function plotter (2d,3d),colored graphs, expression evaluator.
In this file you can find:
- 1) Remove old version (if you have)
- 2) Under Terminal, Launch setup.sh.
Then you can use it (If you have installed old version and you want to see new icons, restart system)
Open examples directory into the Browser and click on all the icons
one by one.
Use Browser application menu for change mode and your intuition for the rest.
You can change the T parameter in real time: after enable box between play and T slider, and move the slider.
The first mouse button allow you to move the view, the secondary and third to zoom it.
The modes:
= : expression evaluation [alt-0]
f(x) : cartesian function [alt-1]
x(t),y(t) : parametric cartesian function [alt-2]
µ(x) : polar function [alt-3]
µ(t),§(t) : parametric polar function [alt-4]
f(x,y) : 3d function [alt-5]
x(t),y(t),z(t) : 3d parametric function [alt-6]
x(t,u),y(t,u),z(t,u) : 3d parametric function [alt-7]
µ(t),§(t),½(t) : 3d spherical function [alt-8]
µ(t,u),§(t,u),½(t,u) : 3d spherical function [alt-9]
Color(x,t) (8bits) : 2d color function [alt-.]
v0.11a new features:(19mai97, perhaps the last DR8 version)
- Bug fixed: you can resize window with no axes, the function size follow
- More faster color mode
- More faster zoom
- Show scale on z axe in Spherical mode (bug on v0.010a)
- move and zoom the function view with mouse
- datas window resizable
v0.10a new features:(19mars97, after some examens)
- "Background App Only" flag of 0.09 removed
- RayTraced 4D-fractals icons
- µ(t),§(t),½(t) 3d spherical mode [alt-8]
- µ(t,u),§(t,u),½(t,u) 3d spherical mode [alt-9]
- Time parameter T (UPPERCASE) for all graphics modes, can be modified
in real time with slider + Checkbox for Automatic/Manual Mode (automatic
not active for T, and manual not active for others parameters).
- color(x,y) mode [alt-.] (original idea by Attila Mezei), trace fct in 256 colors.
The Values are in [0;255]. try: 16*(1+cos x* sin y).
In this mode, the parameters limits are the window limits like f(x) mode
you can save the picture with print screen key and use it in your programs
with a modified palette.
- the forgotten parenthesis crashing bug from V0.09a removed
- gold number constant name: old OR (gold in french), new: Au (chemical symbol of gold)
v0.09a new features:(1jan97)
- x(t),y(t),z(t) 3d mode
- x(t,u),y(t,u),z(t,u) 3d mode
- Show Axes CheckBox
- bug on power evaluation removed.
- graduation on all axes
- z axis direction corrected
v0.08a new features:(27dec96)
- fixe cut/copy/paste full line from editor bug (char ASCII 10)
- new constante:PI_180=PI/180 (x*PI_180 convert ¡->rad,
x/PI_180 convert rad->¡)
- numerical writen numbers can be:18E1¡ or 180¡ ->3.14...(convert to rad)
- bugs on some case of Del function fixed.
- parameters correctly modified when load functions configurations.
- save, save as.
- icon for files
- f(x,y) (2d1/2) [ALT-5] (axes y and z are inverted sorry)
v0.07a new features:(24dec96)
- Special Xmas Icon
- Multiples functions
- load, functions configurations
v0.06a new features:(17dec96)
- In v0.05a more than one Couleur (Color in french) window can be opened
when change mode function, it was a bug. It's removed and the window is
now named Color.
- Color window is hidden in expression evaluation mode.
v0.05a new features:(16dec96)
- Faster update of functions.
- One litte precision bug from v0.04 is removed
- One icon with pixels and colors;-).
- The graph window is correctly updated when resized
- Choice of colors for background and functions(the graph is draw in 8bit)
.
v0.04a new features:(9dec96)
- Ã(x) <=> sqrt(x)
- constants: PI, PI_2, PI_4, e, OR
- xEn: x*10^n
- arithmetic evaluation (= ALT-0)
- Polar functions (µ(t)=radius,(t=angle) ALT-3)
- Polar parametric functions (µ(t)=radius,§(t)=angle ALT-4)
v0.03a new features:(version five o'clock tea @ BeEurope, 6dec96)
- rootn (x) n basis root (usage: see log, root x->root3(x))
- 2 window: 1 for parameters +1 zoomable window for graph
- parametric functions
- pop-up menu: select f(x) ALT-1 / x(t),y(t) ALT-2
v0.02a/v0.01a new features:
- B_NAVIGABLE is set on for BTextControls navigation.
- when an error of range is made-> delete needless 0 on preview
value (ex:10.00000->10.)
- when an error of f(x) is made -> preview f(x), and not f(x)=x.
- sinh,cosh,tanh in this text (active on v0.01a.
Functions:
abs(x) floor(x) ceil(x)
exp(x) ln(x)
log(x)==>log10(x)
loga(x) ex: log5.55(x)
sqrt(x) rootn(x) ex: root3.5(x)
sin(x) cos(x) tan(x)
acos(x) asin(x) atan(x)
sinh(x) cosh(x) tanh(x)
+ in future: asinh,acosh,atanh
Operators:
x! (x must be a positive integer)
x^n
+ - / *
(/x) <=> 1/x
(-x) <=> -x
Ãx
xEn x*10^n ex:5E3 = 5 * 10^3 = 5000
no En, only xEn (no E2 but 1E2=100)
xEn¡ or x¡ (only numeric)==> convert xEn from deg to rad (see "examples/Spirale degres.Math" example)
n in xEn,rootn(x) and a in lna(x) must be numericals numbers.
for all functions:
cos x ==>cos(x)
cos 5 or cos5 ==> cos(5)
but for log:
log 5 ==> log10(5)
log5 ==> error
log5 x ==> log5(x)
PI
PI_2 (pi/2)
PI_4 (pi/4)
PI_180 (pi/180, used for deg to rad translation)
e (Euler number)
Au (gold number)
- If you want select an expression ( by double-click), only a part (the half of
BTextControl width...BeOs DR8 BTextControl->SetAlignment bug ) is
inverted, but all text is selected for cut/paste/copy.
- System crash sometimes when quit calc.(IconWorld and AppSketcher have the
same bug) You can use [Alt-Gr]-[right-Ctrl]-[shift-Ctrl]+click on Calc in menu Be of the Browser to avoid this bug
For bugs, suggestions, gifts...
