SUMMARY

The discussion centers on determining the individual vectors that combine to form a given resultant vector when provided with the angles relating them. Participants suggest two primary methods: constructing a vector triangle and applying the sine rule, or analyzing the components of the vectors parallel and perpendicular to the resultant vector. The conversation highlights the importance of visual representation and component analysis in vector resolution.

PREREQUISITES
  • Understanding of vector addition and resolution
  • Familiarity with the sine rule in trigonometry
  • Knowledge of vector components (parallel and perpendicular)
  • Basic skills in drawing vector diagrams
NEXT STEPS
  • Study vector resolution techniques in physics
  • Learn about the sine rule and its applications in vector problems
  • Practice drawing vector triangles for various scenarios
  • Explore component analysis of vectors in two-dimensional space
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in mastering vector analysis and resolution techniques in both academic and practical applications.

If you're only given the combined vector and you're asked to find the two vectors that made up this combined vectors, and you got all the angles you need that relate the combined vector to the vectors you've combined. Is it possible to get the answer from that info alone? If so, how?

Hi Femme_physics! :wink:

Yes, either draw a vector triangle and use the sine rule, or use components parallel and perpendicular to the combined vector.

Would you like to try one, so that we can see if you're getting it right? :smile:​
 
Ah tiny-tim...you're recognized me in my disguise have you? ;)

Yes, I would! I tried that now..no triangles I draw seem to work!

So I won't get a warning for askig a HW question, try this link:
