Find the angles made by `veca=3hati-6hatj+2hat k` with the coordinate axes (standard basis vectors).
Any vector in 3-D can be written as

Explanation

To find the angles made by the vector \(\vec{A} = 3\hat{i} - 6\hat{j} + 2\hat{k}\) with the coordinate axes, we will follow these steps:

### Step 1: Calculate the Magnitude of the Vector
The magnitude of the vector \(\vec{A}\) is given by the formula:
\[ |\vec{A}| = \sqrt{(3)^2 + (-6)^2 + (2)^2} \]
Calculating this:
