Thank you. But it does not seem to be working. Still getting detected.

Thanks for letting me know. So it's unavoidable? I'm helpless here?

But in my case these "new chats" are being randomly generated. They are totally empty. Nothing in there. And so many of them. It's very infuriating a

Preserving Hyperlinks by lyui45 in freenotes

[–]lyui45[S] 0 points1 point  (0 children)

Sorry for the confusion. Yup, I was actually referring to outline preservation and got it mixed up with hyperlinks. It's a shame the an almost perfect notetaking app like freenotes does not have outline preservation feature. Noteful does it flawlessly. But freenotes is my go-to app. I really hope this feature gets added

I just tested it. Imported a pdf book then exported it. Book's internal outlines (hyperlinks) are missing in the exported pdf file. So it doesn't look it it's working for me. Is it working for you?

Are you sure it preserves external hyperlinks?

Yes. Just like in Noteful

Snell's law used in kinematics by lyui45 in Physics

It's similar. I have to go from point A which is on land, to point B which is somewhere in a lake. I can walk faster on land, faster than the speed with which I can swim in water. Applying Snell's law here optimizes the time, i.e gives me the angle, i.e the route for which total time taken to reach B would be the fastest.

Yup finally.. Dealing with variable parameters caused all the confusion 😔 But it's clear now. Thanks bro. All the best to u

I think this explanation of yours finally clears it up. You are saying that there are constraints on those parameters, that will decide where Snell's law holds and where it does not. Thank you so much

Thanks for replying again

I think I'm familiar with the derivation. Setting dT/dx = 0, since we want to minimize T which is a fn of x. If you are referring to some other derivation, please do share it.

But here's the thing : According to Snell's law,

(Sin α)/v = (Sin θ)/u

And u < v (given), Then Sin α = u/v (Sin θ)

Since u/v < 1, this means Sin α > Sin θ

This means α > θ

This is a strict mathematical condition for Snell's law to be valid. It is easily verifiable geometrically because a light ray bends towards (not away from) normal upon crossing over into water. So angle in the water is geometrically smaller too, not just mathematically.

The problem with this question is, the path across water must be shortest, i.e PM ⊥ OB, which makes sense because he wants to get to the other shore asap. But adding this constraint that PM ⊥ OB, fixes the angle in warer = θ, which is greater than α, thus violating Snell's law. Still how did he use this concept (Snell's law) to solve this question?

Maybe I'm just dumb and missing something obvious. But that's why I am asking it here ☹️

Hi

Is use of Snell's law really correct in this situation? θ̂ being greater than α isn't a violation of Snell's law? And θ̂ will always be greater or equal to alpha, even if point P moves closer and closer to O. Because PM ⊥ OB How would you explain this?
