Remember "Logorithisms"

Clever little thingies, especially when spelt correctly !

I still have my book of 5 figure log tables.


Perversely I've never been able to forget

Tan = opposite over adjacent

Cosine = adjacent over Hypotenuse



and ACTS?

I still remember the function thingies, considering the triangle as
base, perpendicular, and hypotenuse, by

P over H: the sign of a Public House
B over H: the cost of a Boarding House
P over B: we tan the Poor Beast.

And they've still not proved of the slightest use to me. But even so,
I wish I knew maths.
