If you want help about a button, press the Help button and then the button on which you want help.
In the field "f(x) =" you can type in an equation with "x" as the unknown and "a, b, c, d, e, y, z, and t" as constants. You can then solve the equation "f(x) = 0",
find minimas and maximas, calculate the integral and find a simple plot in [Xmin, Xmax].
Press the button "Const" if you want to define some of the constants (a, b, c, d, e, y, z and t) to the formula in the field "f(x)".
Press the button "Root" if you want to solve root(s) to the equation in the field "f(x) = 0".
Press the button "Min/Max" if you want to solve minima(s) and/or maxima(s) to the equation in the field "f(x)".
Press the button "Integrate" if you want to solve integrals to the equation in the field "f(x)".
Press the "Auto y" button if you want a plot of the equation f(x) with auto scaling in y direction in the interval [Xmin, Xmax].
Press the "Plot" button if you want an overview plot of the function f(x) in the interval [Xmin, Xmax].
Press the button "Sum (‚àë)" if you want to calculate a sum.
Press the button "Real Polynomal" if you want to solve roots to a polynomal with real coefficients.
Press the button "Complex Polynomal" if you want to solve roots to a polynomal with complex coefficients.
Press the button "Expression", if you want to study expressions of up to ten variables and solve one of them as function of the others.
Press the button "3-D Root" if you want to solve roots to a system of equations:
