Fucking cosines/sines/tangents

Taken me forever to figure out a simple hypotenuse calculator, yeay yeah I know Pythagoras theorum but on surveys I'm not able to measure the upright length just the width from the ground and the angle in degrees of the roof by placing my digital spirit level on a rafter

My first spreadsheet formula was flawed and I was buggered if I could figure out the issue hypotenuse = width/cos(angle), eventually I realised that spreadsheets need radians not angles in degrees, then it hit me after and hour or two of playing with the functions "DEGREES" and "COS" etc that maybe there's a RADIANS function, and there is, formula is now hypotenuse = Width/COS(RADIANS(angle)) et viola, it works

Now to scrub all the chalk markings off the living room wall before the Mrs see's them 🙂

Cosines/sines/tangents.....I remember doing all that shit for O Levels Maths in 1970.

Can't remember any of it though......but I must have known enough back then to pass.

+1  , I walked out of the door at school and forgot all that .  Don't get me started on algebra, who the f*ck uses that ?

It's simple Bob, with that formula you can calculate how long a wooden leg needs to be to sit on comfortably whilst stuck up your arse 4 inches and leant at an angle of 70 degrees 🙂

Well you are right, Bob is the one to ask about wooden legs.

Incorrect, I've never had wooden leg and my current item is carbon fibre and titanium .  Thank you for your concern 😍

You be careful. If the local scrotes are prepared to jack up a car and cut its catalytic converter off in broad daylight for a few quid, never ever fall asleep outdoors.
