Yes, it will definitely be slower.
However, whether it's "worth it", it will depend on your program and target platform as to whether you'd want to use a lookup table versus calculating the values in realtime.
If you call it a lot, I would say it would behoove you to use lookup tables. It's not hard, it's accurate enough, and it's faster. What could be wrong with that?
Alternatively, you can just use the Sin and Cos commands, see if it's fast enough for your needs, then change it later if you want.
