You can use the component method for finding two or more vectors. Use the X and Y axis. Ex. If you have 5 vectors given-Draw a cartesian plane for every vectors-Get the equivalent value of X and Y for Every vectors(use the SOHCAHTOA rules).-Get the summation of X and Y then use Phythagorean Theorem. For finding the Angle, use the Tan theta. Save
Graphical methods involve examining charts, pictures, and graphs to determine the answer to a problem. This would be used when finding the solution to a system of equations and graphing all the equations to find points at which they coincide. Analytical methods involve calculating answers without the use of charts or graphs. If one were to solve a system of equations by substitution, this would be an example of an analytically produced solution
triangulation method
You can add vectors graphically, by drawing them head-to-tail. Algebraically, you can separate them into components (for example, in two dimensions, the horizontal and the vertical component), then add those.
Sample problems of Graphical and analytical methods are Vector addition and subtraction. These could be done in a analytical or graphical methodologies.

These are called graphical methods, some of which are applications of statistics.
both are used to solve linear programming problems
The graphical method is often approximate but can be applied to any function. If done on a computer, the region surrounding the solution can be enlarged to obtain more accurate estimates. A numerical method will give an exact result is an analytical solution is possible. If not, the solution will depend on the numerical method used and, sometimes, the starting "guesstimate".
The answer is obvious, a picture is worth a thousand words. Being able to lay out in pictora or graphical form the meaning and results of the data make it clear often to laymen. It is also a check on the work in mathematically analysing methods and results.
