Maths of the mind

[robinbloke]

Just as a point of interest, stretch your minds back (or maybe not) to the wide world of Trigonometry, do you still remember the mnemonics for remembering the sin/cos/tan functions as fractions?
If so, what where they?

SOHCAHTOA (pronounced sew-ca-toe-ah) which isn't really a mnemonic so much as a made up word.

There was another one but I can't remember it so I guess it didn't work very well.

SOHCAHTOA

(Just said as a single word, rather like Krakatoa or however the volcano is spelt ;)

Don't think we had these... what were they for?

It's a way of remembering the Sine, cosine and tangent functions

I remember also none of us could spell isosceles (as in the triangles) and our teasher made us remember it by: I Sat On Swanage Cliffs Eating Lovely Egg Sandwiches.

Blimey, the things you remember from ickle school!! :D

SOH CAH TOA was what I used - or just drew a triangle and worked it out if I forgot :-)

I just remembered them.

The ones other people used consisted of the above-mentioned SOHCAHTOA, Silly Old Harry Caught A Halibut Trawling Off America and Tommy On A Ship Of His Caught All Haddock. Bit of a fishy theme there.

Doing Physics, Maths and Chemistry at A-Level, I was inundated with formulae that came with an enormous bundle of mnemonics I never needed, and it became a sort of game amongst the students to see what silly things we could do with them.

That SOHCAHTOA thing, buggered if I can remember anything about Trigonometry though, I haven't had to calculate the lengths of the sides of triangles for a while.

I used trig in anger today, only took me 15 odd years to find an application for it.

Trig in anger? *Is now scared that such a thing can occur*

Expanding quadratics was "Georges" and solving algebraic equations was "Weetabixing".

It's amazing I'm as sane as I am, really :)
