Math problem 5

Convert to rectangular coordinates:
4.2/-75 degrees

I hope you can understand the question. It's kinda hard to type all the symboles.

I got the -75 degrees but what is the 4.2/ about? I am presuming that these are polar coordinates?

Yes, these are polar coordinates.

4.2/-75 degrees(polar coordinates). It wants you to convert them to rectangular coordinates.
It's okay if you want to use your calculator to convert them.

So 4.2 is the radians then?

The polar coordinated are (4.2 radians, -75 degrees)
