Math Problem Statement

Misal suatu vektor secara komponen ditulis AB = (2 3), maka penulisan dalam bentuk analitisnya adalah?

Solution

The problem presented asks to convert the vector AB=(23)\overrightarrow{AB} = \begin{pmatrix} 2 \\ 3 \end{pmatrix} into its analytical form. The analytical form of a vector is typically expressed in terms of the unit vectors i^\hat{i} and j^\hat{j}, which correspond to the x- and y-components, respectively.

For the vector AB=(23)\overrightarrow{AB} = \begin{pmatrix} 2 \\ 3 \end{pmatrix}:

  • The x-component is 2, so the term for this is 2i^2\hat{i}.
  • The y-component is 3, so the term for this is 3j^3\hat{j}.

Thus, the analytical form of the vector is: AB=2i^+3j^\overrightarrow{AB} = 2\hat{i} + 3\hat{j}

Now, comparing this result with the given options:

  • Option c: AB=2i^+3j^\overrightarrow{AB} = 2\hat{i} + 3\hat{j} is the correct answer.

Would you like further clarification, or details on vector notation? Here are 5 related questions to consider:

  1. How do you calculate the magnitude of a vector from its components?
  2. How do you add or subtract two vectors in component form?
  3. What is the scalar (dot) product of two vectors?
  4. How can you represent a 3D vector in analytical form?
  5. What is the relationship between unit vectors and vector components?

Tip: When expressing vectors in analytical form, always match the x-component with i^\hat{i} and the y-component with j^\hat{j}.
