Find the angle that the vector `A = 2hati+3hatj-hatk` makes with y-axis.

Explanation

To find the angle that the vector \( \mathbf{A} = 2\hat{i} + 3\hat{j} - \hat{k} \) makes with the y-axis, we will follow these steps:

### Step 1: Identify the components of the vector
The vector \( \mathbf{A} \) can be expressed in terms of its components:
- \( A_x = 2 \) (the component along the x-axis)
- \( A_y = 3 \) (the component along the y-axis)
- \( A_z = -1 \) (the component along the z-axis)
