Logical inverse relationships
Sometimes, we’ll be able to check behavior by applying its logical inverse. For mathematical computations, this is often the case. We can:
- Verify division with multiplication
- Verify addition with subtraction
Implementation of the square-root function
Let’s take a look at the square-root function using Newton’s algorithm.
Remember that ...
