Find the magnitude and direction of a vector

The video tutorial explains how to find the magnitude and direction of a vector. It begins by introducing the concept of vectors in component form and why it's useful. The instructor then demonstrates how to calculate the magnitude using the square root of the sum of the squares of the components. Finally, the video covers finding the direction by calculating the angle using the tangent inverse of the ratio of the vector's components, rounding the result to the nearest whole degree for simplicity.

Why is it beneficial to convert vectors to component form before finding their magnitude?

• It makes the vector longer.

• It makes the vector shorter.

• It simplifies the calculation process.

• It changes the vector's direction.

What is the first step in calculating the magnitude of a vector in component form?

• Add the components together.

• Multiply the components.

• Divide the components.

• Square each component.

What is the magnitude of a vector with components 7 and 4?

• 65

• Square root of 49

• 13

• Square root of 65

How do you find the direction of a vector using its components?

• By adding the components.

• By taking the tangent inverse of the ratio of the components.

• By multiplying the components.

• By subtracting the components.

What is the rounded direction angle of a vector with components 4 and 7?

• 45 degrees

• 90 degrees

• 60 degrees

• 30 degrees
