Sine rule 

The Sine rule is used to find the length of a side or the size of an angle.

Triangle with sides and angles labeled side a, side b, side c, Angle A, Angle B, Angle C

`a/(sin\ A)=b/(sin\ B)=c/(sin\ C)`

The following mnemonic (picture memory aid) is what we recommend to remember this formula.

We recommend that you do not remember the sine rule formula as you don’t need it 

Zero

That’s correct. We recommend nothing. We recommend that you do not remember this formula. You don’t need it.

See examples NOT using Sine rule.
