**Formula:**`C(row, col)`

## Introduction to Pascal's Triangle Coefficients

The coefficients in Pascal's triangle are calculated using the formula C(row, col) = row! / (col! * (row - col)!), where ! represents the factorial. It represents the number of ways to choose col items from a set of row different items.

## Parameter usage:

`row`

= the row in Pascal's triangle`col`

= the column in Pascal's triangle

## Output:

`C(row, col)`

= the coefficient at the specified position in Pascal's triangle

## Data validation

The column value should be between 0 and row, both inclusive.

## Summary

This calculator determines the coefficient at a given position in Pascal's triangle. It evaluates combinations and is widely used in probability and combinatorics.
