How can I construct vector diagrams?

Answer 1

Vector diagrams should always be drawn to scale, using a ruler and a protractor, as accurately as possible. If an accurately drawn scaled vector diagram is used, the magnitude of the vector can be measured using a ruler, and the direction can be measured using a protractor.

Example:

A car travels 120 km east, then turns north and travels another 50 km. What is the displacement of the car?

This could be drawn using carefully drawn vectors, drawn to an appropriate scale such as 1 cm = 20 km. This would mean drawing a 6.0 cm arrow, pointing east, then a 2.5 cm arrow drawn head-to-tail, pointing north (#90^o# angle between). The displacement is the straight-line, "as the crow flies" distance between the starting point and the ending point, which should work out to a 6.5 cm long arrow pointing approximately #23^o# north of east.

To construct vector diagrams, follow these steps:

Determine the scale: Decide on a scale that allows you to accurately represent the magnitudes of the vectors you are working with.
Draw a coordinate system: Draw x and y axes on your paper to represent the horizontal and vertical directions, respectively.
Draw the vectors: Use a ruler to draw arrows representing the vectors. The length of each arrow should correspond to the magnitude of the vector, and the direction of the arrow should indicate the direction of the vector.
Label the vectors: Label each vector with a letter or symbol to denote its identity, and include the magnitude and direction if necessary.
Add vector components: If you need to find the components of a vector, draw lines parallel to the x and y axes to represent the horizontal and vertical components of the vector.
Measure angles: Use a protractor to measure angles between vectors if needed, and label them accordingly on the diagram.
Check your work: Double-check your diagram to ensure that it accurately represents the vectors and their relationships.
Interpret the diagram: Use the vector diagram to analyze the relationships between vectors, calculate resultant vectors, and solve problems in physics, engineering, or other disciplines.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
