In summary, the conversation discusses drawing force vectors as arrows using F1 and F2, with values of 100 and 200 respectively and corresponding angles of 20 and 30 degrees. The suggestion is to plot these points on a coordinate system and join them to the origin to create the force vectors.

F1Cosx and F2CosX2 and
F1Sinx and F2Sinx2

I need to draw each force vector as an arrow ?
how do I do that?

You need to tell us what F1 and F2 are before we can be any help. Without definitions, these are no more vectors than I am a top hat.

oky, f1=100 x1=20degree
and f2 200 x2=30 degree

Well, pick a coordinate system (say the x-y axis). Then the force F1=(100cos20, 100sin20). Since these are just numbers, you can plot the point (100cos20, 100sin20). Join this point to the origin, and you have your force vector. Similarly for F2

1. What do the letters F1 and F2 represent in the graph?

In this graph, the letters F1 and F2 represent the magnitude of two different force vectors. These vectors represent the strength and direction of forces acting on an object.

2. What does the x-axis represent in the graph?

The x-axis in this graph represents the angle of the force vectors, measured in radians. As the angle increases, the direction of the force vector changes.

3. How are the graphs for F1CosX and F2CosX2 related?

The graphs for F1CosX and F2CosX2 are related because they both represent the cosine function, but with different magnitudes. The F1CosX graph has a larger magnitude, resulting in a larger amplitude and a more spread out curve compared to the F2CosX2 graph.

4. Why are there two graphs for both the sine and cosine functions?

The two graphs for both the sine and cosine functions represent two different force vectors. The sine graph represents the vertical component of the force vectors, while the cosine graph represents the horizontal component. Combining these two components gives us the overall direction and strength of the force vectors.

5. How can this graph be used in practical applications?

This graph can be used in a variety of practical applications, such as engineering, physics, and mechanics. It can help in determining the resultant force acting on an object, as well as the direction and magnitude of individual force vectors. This information is crucial in designing and analyzing structures, machines, and other systems.
