Trouble with drawing vector diagrams.

Click For Summary
SUMMARY

The discussion focuses on interpreting vector directions in physics, specifically the notation "E 25 degrees S" and its equivalence to "25 degrees S of E." The user clarifies that this notation represents a direction 25 degrees below the horizontal eastward axis. The conversation highlights the common confusion among students regarding vector representation and emphasizes the importance of understanding these notations for solving vector-related problems effectively.

PREREQUISITES

Homework Statement


Total time 2min, duck travels 22 m 36degree N of E,then 65m E 25degree S.


Homework Equations





The Attempt at a Solution


i understand 36 N of E but what is E 25 degree S.

"E 25 degrees S" is the same as "25 degrees S of E": If "East" is to the right, then "E 25 degrees S" is at an angle 25 degrees below the horizontal. You can interpret "E 25 degrees S" as "first go E then go S until you reach an angle of 25 degrees".
 
Yes, it's just two different ways of writing vectors. It can be frustrating to new students of vectors. In my school, the math teachers write E25S but I usually write 25 S of E. I'm not sure which is better, sometimes I think I should just do it the way the math teachers do.
