Find the Unit Vector U in the Same Direction as Vector W

What is the formula for finding a unit vector?

• W divided by its magnitude

• W plus its magnitude

• W multiplied by its magnitude

• W minus its magnitude

Why does the speaker prefer to write vectors in component form?

• It is easier to find the magnitude

• It simplifies addition of vectors

• It looks more professional

• It is a requirement for unit vectors

How is the magnitude of a vector calculated?

• By adding the components

• By multiplying the components

• By subtracting the components

• By squaring and summing the components

What mathematical theorem is used to find the magnitude of a vector?

• Fermat's Last Theorem

• Fundamental theorem of calculus

• Pythagorean theorem

• Binomial theorem

How can you verify the correctness of a unit vector calculation?

• By checking if the components add up to one

• By ensuring the components are integers

• By dividing each component by the square root of the sum of squares

• By multiplying each component by the sum of squares
