You are not alone, I am 63 and haven't got a scooby!

Trigonometry, it's all to do with right angles triangles.
The ratio of the lengths of the sides defines the angles and are given names, viz. Sine, cosine and tangent.
The sides are called the opposite, adjacent and hypotenuse (the side opposite the right angle)
So the Sine is the Opposite divided by the Hypotenuse, the Cosine is the Adjacent divided by the Hypotenuse and the Tangent is Opposite divided by the Adjacent.
It's all great fun!!!

Then it all gets complicated when the triangles have angles for sides as well. Then you get Haversines, Cotangents, etc. Spherical Trigonometry, the basis for 'proper' navigation (pre SatNav).... Ooh Arr!

Pre Calculator too !

I bet the Eye patch and Parrot were a hindrance though

Yep. Still got my copy of Norie's Tables. And my slide rule......

Not sure I remember how to use them though......

You can Change the formulas around by substitution ,because of the relationships between the factors ,but my napiers bones are creaking this morning!

All I had was chalk and slate when I went to school in the East End of London. Some don't believe me.

Norie's Tables!!

So that's what they're called..

Show's how much I remember.

I thought it was Godfrey & Siddons? I remember my British Thornton Slide Rule which cost my mum £3.17/6d. Three weeks later I was chucked out of physics class.

Norie's Nautical Tables : https://books.google.co.uk/books/abo...AJ&redir_esc=y

Full of essential stuff and still useable today despite originally published in 1803.

Especially if your batteries are flat.

About a third of a degree per shim if i remember correctly.

Thanks all for the replies. Just have to wait for the rain to stop now, then under it with the spanners again.
