Pythagorean theorem: A2 + B2 = C2
Trigonometry Method. (Resolve the forces along one plane, and then again in a perpendicular plane using cos or sin function. Then use Pythagoras's theorem to work out the hypotenuse (a2+b2=c2). Then use 'Soh Cah Toa' to work out the correct angle of the resultant Force.
Vectors can be added using the component method, where you add the corresponding components of the vectors to get the resultant vector. You can also add vectors using the graphical method, where you draw the vectors as arrows and then add them tip-to-tail to find the resultant vector. Additionally, vectors can be added using the trigonometric method, where you use trigonometry to find the magnitude and direction of the resultant vector.
graphical is accurate because the vectors added are drawn according to a specified scale.
graphical method is applicable only for solving an LPP having two variables in its constraints , but if more than two variables are used, then it is not possible to use graphical method. In those cases, simplex method helps to solve such problem. In simple, in graphical method is used when the constraints contain two variables only. But simplex method can be used to solve constraints having more than two variables.
The two main methods for determining the resultant of vectors are the graphical method, where vectors are drawn to scale and added tip-to-tail to find the resultant, and the component method, where vectors are broken down into their horizontal and vertical components which are then added separately to find the resultant.

The parallelogram method is a graphical technique used in vector addition. It involves constructing a parallelogram using the two vectors to be added, with the diagonal of the parallelogram representing the resultant vector. The magnitude and direction of the resultant vector can be determined from the properties of the parallelogram.
The graphical method is a method used to solve algebraical problems by using graphs.
When solving vector addition problems, you can use the graphical method or the analytical method. The graphical method involves drawing vectors to scale on a coordinate system and using the tip-to-tail approach or the parallelogram method to find the resultant vector. The analytical method involves breaking down the vectors into their components, typically using trigonometric functions, and then summing the respective components to find the resultant vector. Both methods can yield the same result if applied correctly.
When solving vector addition problems, you can use either the graphical method or the analytical method in geometry. The analytical method involves using mathematical calculations, such as component breakdown and the Pythagorean theorem, to determine the resultant vector. This method often utilizes trigonometric functions to resolve vectors into their horizontal and vertical components. Both methods yield the same result but may be preferred in different contexts based on the complexity of the vectors involved.

The graphical method involves using vector diagrams to visually represent the vectors and their resultant. The analytical method involves breaking down the vectors into their components and then summing the components to find the resultant. The trigonometric method uses trigonometric functions to calculate the magnitude and direction of the resultant vector.
