Copïo i clipfwrdd
a\sin(\alpha )=y
Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.
\sin(\alpha )a=y
Mae'r hafaliad yn y ffurf safonol.
\frac{\sin(\alpha )a}{\sin(\alpha )}=\frac{y}{\sin(\alpha )}
Rhannu’r ddwy ochr â \sin(\alpha ).
a=\frac{y}{\sin(\alpha )}
Mae rhannu â \sin(\alpha ) yn dad-wneud lluosi â \sin(\alpha ).
