Answer:
see explanation
Step-by-step explanation:
Note that cos315° = cos45° and sin315° = - sin45° and
cos45° = sin45° = =
Hence
12(cos315° + isin315°)
= 12(cos45° - isin45°)
= 12( - i
)
= 6 - 6i

To translate the graph of a function is part of Rigid Transformations because the basic shape of the graph is unchanged
In this case, we have the graph of:
And we need to translate it to make it the graph of:
According to our rules we need:
- First, to shift the graph of
- Second, to shift the graph of
But is the same as
