Given the following 4 cleaned statements below:

```
t1 <- "government turtle blue ocean"
t2 <- "crazy turtle ocean waves"
t3 <- "massive turtle washington lion"
t4 <- "lion pride massive ocean dinner"
```

The \(TFIDF\) for `"lion"`

in `t4`

can be calculated as follows:

\(TF = \frac{1}{5} = 0.2\)

\(IDF = log(4/2) = 0.693\)

\(TFIDF = .2 * 0.693\)

Calculate the \(TF\) and \(IDF\) weights for `'turtle'`

in `t1`

. Use \(IDF = log \frac{N}{n_{t}}\)
