Probability of selecting one Lewis Carroll book (1/3)

Probability of NOT selecting one Lewis Carroll book (1-(1/3))

Probability of choosing exactly 2 Lewis Carroll books from 4 books

This is known as P*G TRIG.

The graph below may help to elaborate on Alan’s explanation.

Radar guns detect the Doppler shift in frequency to determine speed. The Doppler shift is proportional to the speed of the target’s approach or retreat from the receiver. The moving target will appear to slow and stop as the angle approaches 90, then accelerate again. At this point the cosine values are negative and the Doppler shift in frequency is now negative with respect to the broadcast frequency.

Basic trig functions are used to reconcile the two vector components of a radar beam. The cosine division returns the X vector component of the actual speed. This may seem counterintuitive because the target is not moving in the Y direction, but the radar beam does move in the Y direction relative to the target -- unless it is dead on, then the indicated speed equals the true speed of the target.

Obtaining a dead on fix requires standing in the path of the target. There are cops dumb enough to do this very thing, especially in the early days of this technology. The smarter cops stood in the retreating path. For the former, it’s pigs in a blanket; for the latter, another dozen doughnuts.

Teaching pigs (physics) trig is almost as annoying as teaching them to sing.

Well Rosala, It just sounds like a lot of hot air to me. :)

An Olympic mistake. (Insert curse words here).

I just reread the question. It’s not the same as the other question --Anon’s answer is correct. 

Now, there is another reason to pinch a clothespin on my nose. It seems I have a strain of CDD that causes near instant brain damage. Yep, my brain is liquefying and dripping out my nose. A clothespin will help keep it contained until it re-solidifies.

Maybe I should just let it drip out; then, by shear random chaos, my brain cells might move like individual amoebas, coalescing into a non-corporeal entity like a Boltzmann brain of pure energy with a randomness of memories that do not include exposures to thought-stopping byproducts of CDD viruses.

OK. The link now functions.

There is something about the inflection on permutation that is reminiscent of someone. I’m sure I’ll figure it out, soon.

Anyway, your answer may be a permutation, but it’s wrong. This answer should be appened to the multiple answers for this question that's on another post. It needs three wrong answers and one correct answer, like a multiple choice question.

Your incorrect answer will be the first one discarded -- at least by those who can find their butts in the dark with a torch, a GPS, and an anatomy guide. No buts about it!

OH,OH Revenge is in the shadows! HAHAHA!

I wondered why this was so complicated. Most of the time I can figure the answer just by looking. Along with the clothespin, a pair of untinted spectacles might help.

Well, CPhill, it looks like we have the same strain of CDD.

Thanks Alan!

 The missing Phi constant is a pain, but here are some great ones I use all the time.

The 220 lattice spacing of silicon constant. I use this one the most. It’s especially useful for efficiently sweeping sand out of my beach house.

The Sackur-Tetrode constant (1 K, 101.325 kPa). I use this one to estimate the size of the vacuum cleaner I need.

The Shielded proton mag. mom. to Bohr magneton ratio. I use this one to calculate how close I can stand to my household-sized nuclear reactor that powers the vacuum cleaner.

The electron-tau mass ratio. This is used as a substitute for the dominant hadronic tau decays for the heaver particles that escape the shielded proton magneton generator. It also allows for a basis to make optimum adjustments for when my mother-in-law visits.

Atomic unit of 1st hyperpolarizability This one tells me how hyper-polarized I am in person.

Atomic unit of 2nd hyperpolarizability This one tells me how hyper-polarized I am on line.

Phi estimates the potential effect this has on others. I have to enter the number manually --what a bummer!

I would give an example, but the equations are proprietary, I can’t share them.

LMAO! You could be a standup comedy writer, CPhill --or at least a sit down comedy writer.

Who would ever think permutations could generate so much humor? But they do:
