Search Results for "x root"

Application for polynomial roots calculation. The application does the job by supposing the roots of the derivative function are known. This way, we can delimit the range where each possible root is in, and by applying Bolzano's theorem, we can find the zeroes. It is not a very eficient way, as we must calculate al the derivatives of the polinomial, implying very high numbers (n!), that make the needed precision increase, making the computational complexity for high-degree polinomials poor. But I have been able to make it work with a 40-degree polynomial, with two very proximal zeroes arround x=1000. ...

...The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.putVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.putVariable("x", i); }
