This thread is soooo boring! Soon you all be talking about imaginary numbers.

Yes, all this stuff is over my head as I did really badly in my A-level Maths. Mainly cos I was concentrating on fun stuff.

As I have a mean average working day of 12.243 hours weekdays, & 8.659 hours on Saturdays, of which 7.432% of the time I'm drinking coffee. I would like you 'O' Little miss Boffinofbritain to explain mathematically how you worked out that I was A, being bitchy,
& B, assuming my mug contains 16 fluid ounces of coffee & takes me 9.49785 minutes to drink. How many spoons of coffee I consume in a minute, at 2.975 spoons per mug.

j, much more practical if you want to keep the electricity flowing!

Regarding concepts of the infinite, I remember my school maths teacher hammering it into us that infinity didn't exist, things could only "tend towards infinity". Shame I've forgotten most of the maths he also taught us.

Considering that an overdamped, single degree of freedom system will tend exponentially toward its equilibrium position, reaching it only as time reaches infinity. From a design perspective it is usually said that the system is at rest when time is at 4 time constants, derived from the roots of the systems characteristic equation, at this time the displacement of the system will be at 2% of its initial displacement.

Or, in simpler form ... CLOSE ENOUGH

Isn't that much easier to swallow?

No

Or am i just having a Blackadder "Mr Thickie" moment?!

"as time reaches infinity"?

how do we know it's reaching infinity? Infinity is infinite. It also doesn't exist, so how do we know that ANYTHING is reaching it

"derived from the roots of the systems characteristic equation"?

which is what exactly?! what is the systems characteristic equation that we need to take the root of?

however, it is now friday and therefore approaching beer time, which sadly is a finite time that shall end at some point before the evil root of 900 (measured in hours of the day that is known as monday).

unless of course, like me, you're off next week

Cheers.

I know you say this in jest. But I am quite sure the local bike shop do this as standard practise. That and add a zero to the prices of their second hand machines.
