Functions Calculator is a calculator capable of performing basic operations on a given set of functions, such as generating new functions out of already generated once, and evaluation at a real point in the domain of a certain function.
Following is the list of the calculator's available commands:
"eval(uate) num x "- Evaluates function #num on x
"poly(nomial)N c0 c1 ... cN-1"- Creates a polynomial with N coefficients
"mul(tiply)" num1 num2 - Creates a function that is the multiplication of function #num1 and function #num2
"add num1 num2 "- Creates a function that is the sum of function #num1 and function #num2
"comp(osite)" num1 num2 - Creates a function that is the composition offunction #num1 and function #num2
"log N num" - Creates a function that computes log N of function #num
"del(ete) num"- Deletes function #num from function list
"help" - Prints this help screen "exit"- Exits the program
NOTE: every number in this function is rounded to 2 points after the decimal dot, beside powers in polynomials
The functions are displayed on the terminal in the form of a list, onto which the user can add the wanted function, using commands that operate on a function or a pair of functions.
Function: ADT base class from which all functions in the calculator inherit. it holds the equation for the function, and the calculation/print methods.
Log: The logarithm function. default constructor initializes to natural logarithm, additional constructor recieves a positive value and initalizes to logarithm in the given base.
Sin: The sin function
Polynomial: The polynomial function. has a constructor that gets vector of coefficients.
ComplexFun: ADT base class from which all user-built functions will inherit.
SumFunction: for all functions that are generated using the addition operator
MulFunction: for all functions that are generated using the multiplication operator
ComposeFunction: for all functions that are generated using the composition operator
List: data structure of calculator.
We built a class "Function_list" as data structure. it contains a vector for shared pointers of type Function (ADT). It can add new functions to the vector, remove functions, and the entire program runs based on this class.
