Simple question

[halcyon marlin]

Hey i have a simple question I just have blackout, if I have sin(90-2a) can I turn it to cos(2a)?

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with: ```diff
   +close

You should remember that sin(90-2a)=cos(2a)

Assuming this is deg and not rad
