Notes:

· 'a' represents arc, 'h' represents hyperbolic, unities of 'x' is degrees or radians or gradians, 'y' is a ratio, 'z' is a value, 'm' and 'n' are hyperbolic variables, 'w' is cardinal sine variable, 's' and 't' are statistics variables ("gerror(s)" is the function gauss error), 'r' is arithmetic variable.
· You can use amplitude in the form 5.123*10^-1, for example.
· Calculations mode:
If you in beginning of an enabled function (Useful when you want to solve functions with different calculation modes at the same expression)
a) put rad the application will know that the calculations mode of this function is radians (example: radsin(pi/6)).
b) put deg the application will know that the calculations mode of this function is degrees (example: degcos(60)).
c) put gon the application will know that the calculations mode of this function is gradians (example: gontan(30)).
· All functions are in degrees by default until you configure the mode of calculations for the first time.
· 5.123x10^-16)*sin(34+67)=5.02888x10^-16 is correctly processed.
· Scientific notation can be wrote in many ways, like 5.123x10^-6 or 5.123*10^-6 or 5.123E-6.
· In the argument can be processed arithmetic calculations like sin(30)(=)sin(10+20)(=)sin(100/10+400/20)(=)radsin(pi/18+pi/9)
· You can use scientific notation in the argument in the forms, for example (15E12)*sin(3E1)=7.5E12
· The application process correctly calculations of amplitude and argument. For example (5E1+10E1)*sin(1.5E1+3E1)=106.066
· The application process correctly operations with functions and constants values mixed. For example (3E2)*radsin(pi/6)*degcosec(30)=300, (3E2) is the constant, (pi/6) is a angle in radians and (30) is a angle in degrees.
· To make easy entering parentheses. You can choose '(' with ')' or '[' with ']' or '{' with '}'.
· You need parentheses to make complex calculations.
· Writing square root: Example square root of 2, enter "2^(1/2)".
· To use exponents you need to enter '^'.
· Exponents are enabled for "pi" (ratio of perimeter with diameter (2*pi*r/2*r)) and "e" (Napier's constant).
· The Calculation of exponents is enabled, for example "8^(1/3)=2"
· You can solve complex expressions like "degasin((sen(30))^2+(cos(30))^2)" so this "=90" (degrees).
· The design is made to seem more like a "trigonometry command prompt".
· You maybe need to clean the environment of calculations by entering "clean" or in Portuguese "limpar", and use the previous answer by entering "ans" or in Portuguese "res", and also close the application by entering "exit" or in Portuguese "sair".
· You can use "ans" or in Portuguese "res" in the exponents.
· You can see information about application when entering "about" or in Portuguese "sobre".
· If you want to make an arithmetic operation with the previous answer and a expression, use "+,-,*,/,^" before to enter it.
· The file with the history of the application is in the folder containing the application, the file name is "history.txt".
· The function "cleanhistory" or in Portuguese "limparhistorico" clears the history of the application, the file "history.txt".
· When you are in the environment-resolution calculations you can drag-and-drop a text file (".txt"), that you have saved and closed to the environment-resolution calculations. Then if you click in the window of the environment-resolution calculations and press the button "Enter" the application will process the file, it gives the solution for each expression. The application edits the file that is dragged and dropped to the environment-resolution calculations formatting it and saving it. Note that the application separates the processing of expressions by looking for paragraphs. This feature allows a resolution of expressions very fast and very practical.
· You can make configuration of text colors and background colors entering "colors" or in Portuguese "cores".
· You can make configuration of dimensions (number of lines and number of columns) of environment-resolution calculations's window entering "dimensions" or in Portuguese "dimensoes".
· You can make configuration of window (position (X-axis, Y-axis, width and height) entering "window" or in Portuguese "janela".
· You can erase your configurations of colors, dimensions and window. You just need to close the application and delete "colors.txt", "dimensions.txt" and "window.txt" of the folder that contains the executable of application in use.
· You can use all functions in Portuguese form or in English form in both versions of the application (Portuguese version and English version).
· You can choose how many decimal places you want, to this, take a example, "dp10dpcos(30)". Do you see the "10"? So, if you wrote "dp10dp" in the begining of a expression the answer is given with ten (10) decimal places.
· You can choose the calculations mode (radian/degree/gradian) by enter "mode" or in Portuguese "modo".
· When entering negative values use the symbol "_".
· To use "rest" and "quotient" functions enter "dividendfunctionname(divider)", exampling: "100rest(3)" or "100quotient(7)".
· "logb b(x)" is a advanced logarithmic function because using it you can specify a base, example "logb3b(27)" that "=3".
· This application has some verification of entered data.
· You can create variables in this form: "variablename=expression", example: "fg=45".
· You can see the created variables entering "seevariables", or in Portuguese "vervariaveis", and eliminate all variables entering "eliminatevariables", or in Portuguese "eliminarvariaveis".
· Avoid that the first letter of the variable is one of "a,s,c,t,g,d,q,r,O,H", and don't use in any way in the variables the following letters "e,i,A,B,C,D,E,F".
· You can enable numerical systems response by entering "numericalsystems" or in Portuguese "sistemasnumericos".
· You can use different numerical systems when entering data, just give a letter "B,O,H" exampling: "B1010","O34","HAB". B-Binary, O-Octal, H-Hexadecimal.
· You can use the arrow keys "up" and "down" of keyboard to reuse expressions that you have entered, you can edit them, and so get the wanted answer in a rapid and simple form.
· "rtD D(r)" is a advanced arithmetic function because using it you can specify the degree of root, example "rtD3D(8)" that "=2".
· "afact(r)" is an inverse function for factorial operator "!".
· You can enable SI prefixes response by entering "siprefixes" or in Portuguese "prefixossi".
· You can press "space" key in the environment-resolution calculations, example "cos (30)", "si prefixes", "2 + 2 + 5", isn't problem.
· You can enable actual time response by entering "actualtimeresponse" or in Portuguese "respostahorasatuais".
· You can check actual time by entering "time" or in Portuguese "horas".
· You can get numerical systems answers in scientific notation form.
· You can use previous answers easily, to each answer is provided a name and you can use this name to easily enter expressions.
cos(x) -> cosine of 'x' degrees or radians or gradians.
