Scientific Calculator For Blackberry
By XauravSoft
Scientific Calculator is simple to work over and have high performance tool, it is highly recommended for professionals, It has 28 Mathematical Functions stated below they are quite useful.
Description
Scientific calculator allows performing calculation with high precision and implements most popular mathematical functions: sin, cos, tan, asin, acon, atan, exp, log, sqr, floor and ceil. Also it makes it possible to define your own function, store results in variables and use variable sin expressions. Calculator stores all formulas you have entered. Plot function can be used to draw graph of function with single argument.
Notes
* Write formula using normal infix notation, for example (x^2 + y^2)/1.5. To execute statement, use Evaluate command.
* Use variable to write generic formulas, by changing values assigned to the variables you will be able to repeat calculation for all input data with minimal typing. Define your own functions which also can speedup your work and reduce probability of making an error.
* It is possible to write small functional programs using conditional ?: operator. For example sum of arithmetic progression can be calculated by the following function
sum(x)=x>0?x+sum(x-1):0
Calculator has only < and > comparison operators (because comparing floating point number for equality is any case bad idea). But it is also to check that value belongs to specified range using min<x>max operator.
* All statement you have entered and stored in database. You can select proper statement using List command. Statements are marked with three different icons: ? (yellow) - statement was not yet evaluated, V (green) - statement was normally compiled and ! (red) - statement was not compiled due to some errors. It is possible to insert reference to the users function using Insert command. To compile and execute statement use Edit and then Evaluate command.
* Help command can be used to list all operators and functions provided by the calculator. You can also insert in edit buffer template of operator or function using Insert command.
* To draw graph of user defined function with one argument, use plot function with three or four parameters: plot(from,till,step,function) or plot(from,till,function). In last case step is choosen automatically according to screen resolution.
Instructions
1. Type the Expression in Given Format using keypad or select it from help, and then insert.
2. Press track wheel and select evaluate, here you have your answer
3. You can se help to how to use functions Stated above
Examples:
To calc 21 to the power 4
Type 21^4
press Evaluate.
You can also select command from help menu
In addition you can evaluate long expressions like
log(20)*(6^2)+23/7 or something more complex.
