If one of the three things does happen, that is the monom coefficient is invalid or r invalid power or the string has invalid spaces, we throw an error type NumberFormatException and the software stops.

*In examples a denotes the coefficient and b denotes possession

Examples of invalid inputs:
7tl,4^2,(4+8),84,3/5,4..4,(6-7),(2+2)x^4,x^23,3t,3t^7,x^23,xx,ax ^b,ax^ b,ax^-b, ax^b .

Examples of good inputs:
a,-a,ax,-ax,x,-x,ax^b,-ax^b,x^b,-x^b,a x^b

Our initFromFile read from file complexFunction line by line, No additions like f (X) and so on

How equals work: this method check if given Object c is equals to this ComplexFunction. The test is done by checking whether within a certain number range the two functions return the same Y value when both have the same X value.If one of the values returns the function FALSE then another check is made if 16 digits after the point are equal, then the test continues. This is all wrapped up in try..catch because if one of the values resets one of the functions and causes a divide by 0 the test will not stop. We will note that if it is precisely this value that indicates that our functions are not worth our function, you will not be able to recognize them.

This test is not 100% believable because for us to say that the functions are equal, we must conclude that for all value X, the two functions return the same value Y, which is not possible in computer science, so we took a representation range of numbers.
