Components Method.... ahhhhh.....

Components Method
> one way of getting the resultant vector...

What's???

Vector > direction and magnitude

Scalar > numbers or quantities

How 2 use components method???

To get the resultant vector, we should find first the x-components and y-components of the vectors.

x- component formula usually uses the cosine formula.

y-component formula uses the sine formula.

Sum up the x-components & the y-components. Get the square of the x -components and the square of the y-components... Then get its square root...


The answer is the resultant vector...


to get the direction...


tan-1 (ry/rx)


.....



ok...



thats it!!!
