Examples

Suppose a company purchases a fleet of cars for $560,000. The cars have a lifetime of 12 years and a salvage value of $30,000. They are depreciated as follows:

- `SYD(560000, 30000, 12, 1)` - Returns 80000. The first year's depreciation is $81,538.46.
- `SYD(560000, 60000, 12, 5)` - Returns 56000. The fourth year's depreciation is $54,358.97.
- `SYD(560000, 60000, 12, 12)` - Returns 8000. The final year's depreciation is $6,794.87.
