I think SOHCAHTOA is much easier to remember, and tells you which ratio is for sine, which is for cosine and which is for tangent.

Another way to remember them that a student taught me is...

Since \( \sin{\theta} = \frac{O}{H} \), it looks a bit like a stick figure boy, and "boys sin".

Since \( \tan{\theta} = \frac{O}{A} \), it looks a bit like a stick figure girl, and "girls get tans".

As for \( \cos{\theta} = \frac{A}{H} \), if someone asks you a question, you're like "Ahhh, Cos!"
