regression analysis
one dependent and one or more independent variables are related.
Least Squares method
Simple linear regression is performed between one independent variable and one dependent variable. Multiple regression is performed between more than one independent variable and one dependent variable. Multiple regression returns results for the combined influence of all IVs on the DV as well as the individual influence of each IV while controlling for the other IVs. It is therefore a far more accurate test than running separate simple regressions for each IV. Multiple regression should not be confused with multivariate regression, which is a much more complex procedure involving more than one DV.

No, it is not.
one dependent and one or more independent variables are related.
The independent variable determines the value of other variables and is change by the person doing the experiment. The dependent variable is what is affected by the independent variable; it "depends" on the independent variable.

Your question isn't valid because you need an experimental procedure in place before you determine the variables.
An algorithm, perhaps.
The roots of an equation in two variables is calculated by setting the dependent variable, y, equal to 0 and then solving the resulting equation for the independent variable, x. The procedure for solving the equation in x will depend on the nature of the equation.
Bezier
It is a step-by-step procedure for carrying out some mathematical process.
To choose the appropriate statistical test, the following four question must be answered; What are your dependent and independent variables? What is scale of measurement of the variables? How many groups/samples are there in the study? Have I have met the assumptions of the statistical test?
The parts of a mathematical investigatory project include problem, objective, methods and procedure. It also includes results, conclusion and recommendations, as well as bibliography.
