Use langle and rangle command in LaTeX

We have to use an angle bracket for the inner product. You can use the \langle arg1,arg2 \rangle command for this but if the equation is borough size then I will not recommend this command.

In the excerpt below, you can see that the size of the angle bracket in the fraction is not adjusting properly.

   \[ \langle u , \; v \rangle \]
   \[ \langle \frac{1}{n} u , \; \frac{2}{n} v \rangle \]

Output :

Use inner product in latex.

Use adjustable inner product symbol

You need to use the \left\langle arg1,arg2 \right\rangle command to automatically adjust the angle bracket according to the size of the equation.

   \[ \left \langle \frac{1}{n} u , \; \frac{2}{n} v \right \rangle \]
   \[ \left \langle \frac{1}{b_i} , \; \frac{2}{b_j} \right \rangle \]

Output :

Use inner product with auto adjust bracket in latex.
