Ah! I've spotted the errata of your weighs!
Please...let me guild you along the right-angled path, seivad...
First, you need to be riding a hippopotamus, whereupon you then quickly use a scimitar to cut a square shape (such as the flag of the Vatican City) in half. The key is to measure and guage the slashing cut using the little-known and modern-ancient-local-global
International System Imperial (ISI) (as used by the Shadow People of Lesbos Atlantis Dorado - the original "laddettes"). Only then, seivad, will you have created the lesser-spotted QT - the Quadrilateral Triangle, which is itself a derivative of the long-lost MBT - Manilow's Bermuda Triangle.
I do hope you managed to be up to following the complexities of my idiot's guide.
For further instruction, just PM me: ie, send Corbyn round in a taxi.

Also...
You need to appreciate that said is also busy - figuring out the new software to accept drawings.
Patience, please!

From Pi x radius of the hole squared x height, we get the height as volume of earth removed in cms cubed, divided by Pi x radius squared.
but, have to say, using that formula only works if the radius is constant for the depth i.e. when the hole is cylindrical.
In my experience, most natural holes tend to be a distorted conical shape with the top wider/narrower than bottom. #JustSayin
I'd explain further but am having digestion issues due to popcorn excesses.

Mmmh! I have heard about that bloating effect - butterfly or snowflake?

That is all sorted now - I have reloaded MatLab on my computer. Feel free to borrow it if you want.

Wrong again! I was teaching only last week! Yes, you can also use the secant/tangent formula to calculate the distance to the horizon....and it works because your distance d is a tangent!

And sometimes there's the further difficulty of finding a way to measure the hole that is continually being dug.
There's probably an obvious solution to that further difficulty.

I think you've sold yourself short, there. As I see it, you've done a brief couple of spots of teaching this week, too .

You were teaching while students are on holiday?? Not sure what your perception of teaching is, a teacher would have understood my application, whereas you did not.

Said,
Is this a five minute argument or the full half hour? Why do you go out of your way to ridicule and belittle anyone who disagrees with you?
Let's stick to facts:
FACT: you know nothing about me
FACT: last week I was a Tutor on a university summer residential school, teaching about (among other things) wave propagation, so I do understand about trigonometry and geometry
FACT: I have no problem with your distance to the horizon caculation, which is a good approximation, I have used it myself. Therefore 'I do understand your application'
FACT: a straight line from a point above the earth's surface to the horizon is a tangent to the earth's surface. Distance 'd' in your calculation is such a line, i.e. a tangent
FACT: you don't appear to understand that it is a tangent. To quote you: 'I know exactly what a tangent is, if you mean mathematically - but there was no need to use that in this formula.'
Sorry to sound educational...but your emoji suggested that you were confused.
Best wishes,
Snig's foot

If you are indeed a trained professional teacher - then you would have attended psychology training. You would also know full well the aim of teaching any lesson and would have realised my intentions. Every teacher knows the basics of teaching.
As for belittling people. Recall 'Actually, your line of sight 'd' in this formula IS a tangent to the earth.'
and 'Yes, you can also use the secant/tangent formula to calculate the distance to the horizon....and it works because your distance d is a tangent! and 'you know nothing about me' THAT is belittling!
I am also very familiar with the wave theory., If you are using trigonometry then you are probably teaching secondary level physics, maths or international students as an indication of University life. If it was for a higher level, you would have mentioned the quantum state of physics which cannot be taught in a matter of a week or two. If you want a battle over mathematical prowess - I don't know everything but I would give you a run for your money, so I'm well up for it and would enjoy it!
So 'confused' - yes, as a trained teacher you would not have tried to over rule that which is fundamental to the profession. and would have respected my intention.

Walter, Walter, Walter... methinks thou dost protest too much!
Can you explain to me why someone who claims to have "mathematical prowess" misspelled hypotenuse, not once, but twice. Maybe one mistake could be explained as a simple keying error. Twice suggests an unfamiliarity with the word, which might be understandable from someone who may not have used the word since their school days, but not from a math teacher.

There is a hell of a draught in here - has someone left the closet door open again? Oh, hello seivad nice to hear from you, to hear from you - nice! Your question - ah yes, Left side of Brain and Right side of Brain - some people are talented with numbers while others are talented with words. My spelling is atrocious - remind me to go to confession tomorrow and thank heavens for spell check! and I am terrible at crosswords too, I am also hopeless at names. No doubt I will have the FBI around to arrest me. I am in the habit of spelling 'hypotenuse' with an additional 'e' I have always written it that way OK! What is the weather like in Canada - in the summer here, we had some unusual weather - warmish tuning to warm, now we have warm turning to coldish. I have got some aspirins if you want them.

There's also people who are talented with both.
And people who are talented with neither.
