how to use graphical method?

Graphical Method of Solution of a Linear Programming Problem - So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize o..

First, the data of concentrations versus time is obtained by a suitable method. Then, the data is plotted as concentration versus time. From the resulting plot, the instantaneous rates are determined by drawing tangents to curve and then calculating their slopes. The reaction rate s..

Results and observations of scientific experiments should be properly recorded under headed columns and numbered rows. The headings must include the units in which each quantity is measured. Graphs are very helpful in comparing measurements. The general rule in plotting the graph of a given data ..

Isolation Method - For reactions where many reactants are involved, the order of the reaction is determined by the method of isolation. This was developed by Ostwald. In this method, the concentrations of all the reactants except one are taken in excess. For e.g., in t..

The quadratic expression ax 2 + bx + c can be expressed in the form a(x 2 A 2 ) by the method of completing the square. The integrals can be evaluated by using the special integral..

Graphical representation is more informative than tables as it gives a visual representation of two quantities (e.g., distance vs. time) At a glance a graph gives more information than a table. Both the graphs shown here represent the increasing speed Similarly, fig (2) gives a..

So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize) the objective function Z, then we say that these values of x i are the ..
