**Title: Using the Gram-Schmidt Process for Orthogonalization**

**Objective:**
Learn how to use the Gram-Schmidt process to transform a set of vectors into an orthogonal basis.

**Given Vectors:**
- \(\vec{u_1} = (1, 0, 0)\)
- \(\vec{u_2} = (3, 7, -2)\)
- \(\vec{u_3} = (0, 4, 1)\)

**Task:**
Transform the given basis into an orthogonal basis using the Gram-Schmidt process. 

**Instructions:**
1. Begin with the first vector \(\vec{u_1}\). It remains unchanged as \(\vec{v_1} = \vec{u_1}\).

2. Apply the Gram-Schmidt process to find \(\vec{v_2}\) by orthogonalizing \(\vec{u_2}\) against \(\vec{v_1}\):
   \[
   \vec{v_2} = \vec{u_2} - \text{proj}_{\vec{v_1}}(\vec{u_2})
   \]

3. Continue the process for \(\vec{u_3}\) to find \(\vec{v_3}\):
   \[
   \vec{v_3} = \vec{u_3} - \text{proj}_{\vec{v_1}}(\vec{u_3}) - \text{proj}_{\vec{v_2}}(\vec{u_3})
   \]

5. Verify that \(\vec{v_1}\), \(\vec{v_2}\), and \(\vec{v_3}\) are orthogonal by ensuring the dot products are zero.

This lesson illustrates the step-by-step Gram-Schmidt orthogonalization process to convert a basis into an orthogonal set, providing a foundation for further mathematical applications in vector spaces.
