Question
### Vectors

**Task:**

1. Read the Vectors Section of Chapter 3 of the PHYS 201 textbook (Physics by Giancoli).
   
   In the figure below, a vector and its components are shown. Write down the expression of the components \( A_x \) and \( A_y \) in terms of the magnitude \( A \) and the angle \( \theta \). Also, write the expressions of the magnitude of the vector \( A \) and the angle \( \theta \) in terms of the components \( A_x \) and \( A_y \).

#### Figure Explanation:

The figure is a graphical representation of a vector \( \vec{A} \) in the Cartesian coordinate system. The vector \( \vec{A} \) is shown in blue, forming an angle \( \theta \) with the positive x-axis. This vector is broken down into its horizontal and vertical components, \( A_x \) and \( A_y \) respectively.

- **Vector \( \vec{A} \)**: Shown as a blue arrow originating from the origin (0,0) and extending to a point in the first quadrant.
- **Component \( A_x \)**: The horizontal component of vector \( \vec{A} \), shown as a blue horizontal arrow extending from the origin to the right along the x-axis.
- **Component \( A_y \)**: The vertical component of vector \( \vec{A} \), shown as a blue vertical arrow extending upward from the x-axis.
- **Angle \( \theta \)**: The angle between the vector \( \vec{A} \) and the positive x-axis, located in the first quadrant.

The right triangle formed by these components aids in visually understanding how vector \( \vec{A} \) can be expressed using \( A_x \) and \( A_y \).

#### Required Expressions:

- **Components \( A_x \) and \( A_y \) in terms of \( A \) and \( \theta \):**
  \[
  A_x = A \cos(\theta)
  \]
  \[
  A_y = A \sin(\theta)
  \]

- **Magnitude \( A \) and angle \( \theta \) in terms of components \( A_x \) and \( A_y \):**
  \[
  A = \sqrt{A_x^2 + A_y^2}
  \
