## Several Methods of Depreciation of an Asset

### Description

Return the depreciation of an asset for a specified period using different methods. `SLN` returns the straight-line depreciation `DB` uses the fixed-declining balance method and `SYD` returns the sum-of-years' digits depreciation.

### Usage

    SLN(cost, salvage, life)
    DB(cost, salvage, life, period = 1:life)
    SYD(cost, salvage, life, period = 1:life)

### Arguments

`cost` | initial cost of the asset.
`salvage` | value at the end of the depreciation (sometimes called the salvage value of the asset).
`life` | number of periods over which the asset is depreciated (sometimes called the useful life of the asset).
`period` | period for which you want to calculate the depreciation. Period must use the same units as life.

### Value

val
