\widetilde{ac}

The \widetilde command is used to place a tilde accent over a group of characters or symbols. In the case of \widetilde{ac}, it places a tilde over the letters 'a' and 'c', often used in mathematical contexts to denote an approximation or a modified version of a variable or function.

Examples

Indicating that the value of 'ac' is approximately 0.5 with a tilde accent.

\widetilde{ac} \approx 0.5

Representing an average or modified version of the product of sequences a and c.

\widetilde{ac} = \frac{1}{n} \sum_{i=1}^{n} a_i c_i

Using a tilde to denote a modified version of 'ac' in a mathematical expression.

\text{If } \widetilde{ac} \text{ is used, then } ac \text{ is modified}
