i got the same thing!!!modulus wrote:Qd = 60 * (1 - exp(_I/3000*df)
exp(_I/3000*df) = 1 - Qd/60
-I/3000*df = ln(1 - Qd/60)
3000*df = -I / (ln(1 - Qd/60))
df = -I / (ln(1-Qd/60) */ 3000)
I've used more parentheses than striclty necessary for clarity.

From third last line:
-I/3000*df = ln(1 - Qd/60) multiply both sides by 3000/-I
1/df=((3000*ln(1-Qd/60))/-I)
df=1/((3000*ln(1-Qd/60))/-I)

Lol, yes but i just prefer the inverse cos it looks nicer 1/(A/B). I am fond of brackets, the more the merrier!modulus wrote:Confusion is in the mind of the beholder, grasshopper.
Whilst they both give the same answer (ain't maths wonderful!), yours is in the form of:
x = 1/A/B
which to me looks like an unnecessary inverse. What's wrong with
x = B/A ?

why don't you just write x=(A/B)^-1 to really be confusing.Ich fahre ein Kdf ein Tag wrote:Lol, yes but i just prefer the inverse cos it looks nicer 1/(A/B). I am fond of brackets, the more the merrier!

:thumbLaughed me butt off!!!. I love the way that a fictional sci fi series can keep boffins guessing and trying to find ways of justifying if it can be made to be true. Sounds an awful lot like Scientology!!😂4ThALaStTiMe wrote:the Ultimate Answer to Life, the Universe, and Everything

Bracketed by twin primes, this composite number's factorization makes it a sphenic number, as it is the product of the first three terms of Sylvester's sequence. It is also the third 15-gonal number, a Catalan number, a meandric number, an open meandric number. It is believed to be the third moment of the Riemann zeta function, based partially upon evidence from quantum mechanics.
In base 10, it is a Harshad number and a self number.
It is also a perfect score on the USA Math Olympiad (USAMO) and International Mathematical Olympiad (IMO).
