This is why I never get enough training done, theres so much other random stuff in the world to get distracted by
Spot on, if iāve understood your workingsā¦ the answer is in realising that you can calculate the angle of a 4,4,6 triangle and hence the area of both the circle segment and the triangle without the overlapping area.
You could have made it easier by using 2 x angle to calculate area of āpizza segmentā and subtracted the area of triangle and doubled, but same effect
Easy!!!
I remember this off the top of my head as itās also a proper goody
Itās a class size of 30 pupils for 70%.
So Iād say two pupils in a class will share a birthday.
57 pupils is 99%
366 people and itās a dead cert
The Monty Hall Problem can do one
Why do all these maths problems involve goats?
Stick to counting sheep and life is easy (n+1)
What, you mean like animals? I assumed we were talking about Jan Frodeno and Mark Allen
I didnāt do Maths Aā level - I did Physics instead (purely my preference). I wish I had taken Maths however as studying Biochem at Uni meant having to do physical chem and biochem and much of that was maths related where I struggled without the Aālevel.
always remember being introduced to Schrodingerās wave equation in one chemistry lecture and thinking WTF? triple integration eh?? I could barely do single integration ffs.
I secretly really enjoyed mathsā¦ just havenāt really ever needing to use it since Uni beyond the basics!
likewise.
Struggling to get my hands back on my pure maths A level textbook. If it wasnāt for this damned lockdown I would have torn my parents house apart to locate it.
I still do!
The stuff I do is fairly simple, though the logic problems Iām faced with daily keep me entertained.
Thatās pretty much how I did it. But I forgot about radians being a multiple of pi, and so I wasnāt getting the easier simplifications youāve got with your approach., where the piās from the area of a segment of a circle equation are offsetting the pi in the angle component. In degrees it was all getting rather complicated and I wasnāt convinced the complex expressions I was left with were accurate.
Reinforces the point made before about āuse it or lose itā. I remembered radians being ābetterā for some reason, but couldnāt recall exactly why!
Anyone know how to convert a quaternion to an angle in one of the planes which I can use to get an angle of the steering of the handlebars from a phone mounted on it. Iām sure it should be possibleā¦
IIRC, its quite a simple bit of maths to do thisā¦ I think theyāre called Euler angles?
Christ on a bike i feel thick on here sometimes!
Aha, thanks,

Looks like I simply want āheadingā from there.
As always in the internet age, simply knowing what something is called is all you really need.
I did initially but realise itās all entirely irrelevant to me and what I do
Knowledge and intelligence aināt always the same thing!
The baking thread may as well be in Swahili, far as Iām concerned. Same with football, NFL and wine
Are you making a steering plate for Zwift?
Same
Nahā¦ heās dropped his phone down the bogā¦
