Find the general solution of
cos54cos@ + sin54sin@ = sin2@
Hello differentiateMy best guess is that you want the general solution ofin which case, as pickslides has suggested:
Now the general solution of
is (in degrees):So here we get:
Taking the sign:
Taking the sign:
So there's the general solution: or
(noting that this is now a 'new' )
