Question

Even though the first one hasn't been solved completely...it's about time to change up the menu ;P

1. (eiθ-e-iθ)/2i 77

2. <a>∙<b>=||a|| ||b|| 52

3. 93 110 y=mx+b

4. A+B=90° 241

5. 85’S d(1/x)/d(x)

6. absinθ n 106

7. 97 x2+y2+z2=r2

8. 312 n!/(k!(n-k)!)

9. 111 Σxip(xi) ‘S

10. 206 a for f(z)=1/(z-a)

11. 39_0 Σaii

12. 102 1/(2πi)*∫f(z)dz

KICKBALL!!! (19+53+6+19)

Thanks for the hint ;)

I was

AtMosphere, but this will make 127 instead of 97

Another good one that I hadn't thought of! ;)

Yep...that's what I had in mind...(probably b/c of the draft in HH XP)

Good job :D

and n!/(k!(n-k)!) is the binomial coefficient, so I'm thinking it might have to do with efficiency, but 312 is way to large of a number to try and tackle in one sitting.

Lol...you're right that it's the binomial coefficient...but it's also something else...look to the title of this puzzle for a hint ;P

I'm terrible with the numbery bits, but maybe these will be of help to someone else...

2. dot (or inner) product

6. cross product

9. expectation

11. trace

I have no clue what 5 is. It would surprise me if Y-san meant it to be "log," but we all make mistakes on occasion...

10 & 12 sort of look like bits of Cauchy's theorem/integral, but not quite... Maybe I'm imagining things though, and should just keep it real... <_<

i was thinking the same thing about 5, since d/dx(1/x) is simply -1/x^2, but it's written as d(1/x)/d(x) in the puzzle :-\

still working on it...

"a" in this exp​ression is the asymptote of the graph, but what kind of phrase uses the term "asymptote"??

then again,

Vertical, since "a" defines the vertical asymptote. But then what phrase would END with "vertical"?

SHIP's Log

Now this answer would have fit in perfectly with your answer for #5......

and yes, have read the Rama series. have'nt read Ringworld, but now have a book for my next flight.

it was also in a star trek next generation episode.

I think I've got #6...

Bearing NNW

Nice puzzle, BTW!

combinations

Your answer to #6 doesn't make sense

"NNW"=88, not 106. "SSW"=106 though, but I'm not seeing how you got "Bearing" from the result of a cross product.

Ooops :blush:. You're right,

Bearing SSW - "Bearing" is a synonym for vector, which was hinted at earlier

ah, gotcha.

So thus far,

1. (e-e-iθ)/2i 77 Sign HeRe

2. <a>∙<b>=||a|| ||b|| 52

3. 93 110 y=mx+b very close to being PICK UP Line...perhaps the 110 should have been 107?

4. A+B=90° 241 Complimentary BeVErAgEs

5. 85’S d(1/x)/d(x) SHIP's Log (even though the math clue should have been ∫(1/x)dx)

6. absinθ n 106 Bearing SSW

7. 97 x2+y2+z2=r2KICK Ball (or DySON Sphere)

8. 312 n!/(k!(n-k)!)

9. 111 Σxip(xi) ‘S BeYONd expectations

10. 206 a for f(z)=1/(z-a)

11. 39_0 Σaii

12. 102 1/(2πi)*∫f(z)dz No Residue

Am I missing any?
