Whether they were useful or not, throughout your maths education you've probably come across various mnemonics to help you remember formulae or rules. Which ones can you remember? Extra marks for posting dirty mnemonics as long as they don't break the community guidelines

Some common maths mnemonics:

Circumference of a circle: Cherry pies are delicious
Area of a circle: Apple pies are too

SOHCAHTOA : Some of her children are having trouble over algebra

Remembering the CAST order: All students take calculus

The first 8 digits of Pi : May(3) I(1) have(4) a(1) large(5) container(9) of(2) coffee(6)

Or how about the quadratic formula to the tune of Pop goes the Weasel!:

"x equals minus b, plus or minus the square root, of b squared minus four a c, all over two a.

ILATE for integration by parts. The order of choice for u is Inverse, Logarithmic, Algebraic, Trigonometric and Exponential.

And of course the GOAT: BIDMAS.

tbh, not really sure if its a mnemonic but stick it kiss it flip it really helped me remember how to divide fractions

What is CAST?

Edit: for sec squared equals 1 plus tan squared, "to have sex, you need to have a tan, and then some."

Also, not a mnemonic, but to remember the difference between convex and concave, think about the shape of the modulus function, which is conVex.

In probability theory, if E1, E2,... is a sequence of events, then you can remember the difference between limsup and liminf by noticing that in liMsUp, the intersection (M looks a bit like \cap), and U looks like a union. M comes before U so  \text{limsup} E = \cap_{n} \cup_{m>n} E_m

A mnemonic is any kind of memory technique used to used to retrieve a particular piece of information so these would both be classed as mnemonics.

What is CAST?
Cosine, All, Sine, Tan. The trig functions that are positive as you work round the circle, laid out on x,y axes, and starting from lower right, x-postive, y-negative, and going anti-clockwise.

Wow I just confused myself with this, mainly cause I got anti-clockwise and clockwise mixed up. (I need to sleep...)

But I love having now discovered LIATE for interfraktionellen by parts. But I can only do it to the song I integrate by parts (tune of total eclipse of the heart!)

Ahh, now you mention it I do vaguely remember drawing CAST diagrams in GCSE

In primary school, we were taught:

Hey diddle diddle
The median’s the middle
You add and divide for the mean
The mode is the one you see the most
And the range is the difference between!

We also remembered 7 x 8 with Steps 5, 6, 7, 8

Not particularly useful, but pi to 740 places, in the style of The Raven, by E.A. Poe.

Near a Ravan

But if you're going to start remembering long numbers, there are more efficient memory techniques, converting digits to consonants, and creating words, images,....

Ahh been a while since I’ve seen that one. I only ever heard the start though.

Was amusing when the teacher asked who knew a way to remember sohcahtoa and someone eagerly went to say that one then realised better and had to improvise something.

Back in year 9, I used to have trouble remembering SOH. So my teacher said “sex on holiday”. Never forgot it since...
