Advanced Calculator is a step farther in complexity comparing to the Simple Calculator. The Advanced Calculator has two editing windows. One is for editing x, and the second is for editing f(x). In the x window you can enter any number or formula which contains numbers. In the f(x) window you can enter formulas containing numbers and formulas containing x. First, x will be calculated. Then the result for x will be substituted into the formula for f(x). The presence of two editing windows demands switching between windows. You can do it by clicking buttons "go to x" and "go to f(x)", or by clicking inside the the window. If you forget to enter x, then the x=1 will be assumed. If you forget to enter f(x), then f(x)=x will ne assumed.
Advanced Calculator works in scientific mode. All numbers in internal calculations are treated in scientific format, like 1.23456789012345E+2 for 123.456789012345. You also can use scientific notation in formulas. If you get result NaN, like in ln(-1), that means that the function is not defined for given argument. Otherwise Advanced Calculator is similar to Simple Calculators. There are options to save and print calculation history, to change font, and standard editing options.
Advanced Calculator has practically unlimited power. It calculates formulas like on the picture below in a fraction of second.
