u1^2v3+u2v2+u3v1 buktikan apakah termasusk ruang hasil kali dalam

Untuk membuktikan apakah ekspresi \( u_1^2v_3 + u_2v_2 + u_3v_1 \) merupakan produk dalam (inner product) dalam ruang vektor, kita perlu memeriksa apakah ekspresi ini memenuhi empat sifat utama dari produk dalam:

1. **Bilinearitas (Linearitas dalam setiap argumen):**
   - **Linearitas terhadap komponen pertama**: \[ \langle \mathbf{u} + \mathbf{u'}, \mathbf{v} \rangle = \langle \mathbf{u}, \mathbf{v} \rangle + \langle \mathbf{u'}, \mathbf{v} \rangle \]
   - **Linearitas terhadap komponen kedua**: \[ \langle \mathbf{u}, \mathbf{v} + \mathbf{v'} \rangle = \langle \mathbf{u}, \mathbf{v} \rangle + \langle \mathbf{u}, \mathbf{v'} \rangle \]

2. **Simetri:**
   \[ \langle \mathbf{u}, \mathbf{v} \rangle = \langle \mathbf{v}, \mathbf{u} \rangle \]
