    3:40 actually remember that this only applies to real inputs, as it is possible to solve for sin(x)=2, so sin(love) is only between -1 and 1 if Love is real. Now to prove whether Love is real...

      Ryan Roberson Hahaha, but don't you believe that love is real? 😂

      I believe sometimes love can be very *complex*

      blackpenredpen Do both you and Dr. Peyam work at the same school?

    • @blackpenredpen

      Unfortunately, no.
      But we knew each other back in our undergrad years,
      11 years ago! lol

    I remember sandwich theorem or squeeze theorem from my grade 11 maths..with example of very interesting function lim x->0 sinx/x =1

    • @drpeyam
      @drpeyam  7 ปีที่แล้ว +1

      That's one of my favorite math proofs of all time! I'll definitely do that one someday!

    • @Zonnymaka
      @Zonnymaka 7 ปีที่แล้ว +1

      Speaking of fave theorems....why don't you (evil Dr. Peyam) open a chapter dedicated to the most awesome math proofs ever! I have a weak spot for the Cantor's diagonal argument...

    • @drpeyam
      @drpeyam  7 ปีที่แล้ว +2

      Great idea!!! And OMG, me too! ♥️

    • @Zonnymaka
      @Zonnymaka 7 ปีที่แล้ว +1

      :) Cantor invented a procedure which has been employed many times after. For instance the Goedel Theorem....which is based on the very same idea

    • @drpeyam
      @drpeyam  7 ปีที่แล้ว +1

      Plus the cool thing is that the same technique arises in many different math subjects, like logic, discrete math, analysis, to name a few!

    I like the idea of this squeeze theorem, an I look forward to finding greater application. Maybe with my family of the 'deeply recursive' functions like Q.

    • @JBaker452
      @JBaker452 7 ปีที่แล้ว +1

      Also, I have now been thinking that this squeezing idea might help with the analysis of these deeply recursive functions (like Q). I doubt this would work for Q as I explained that one, but within the family of such functions it might be possible to squeeze some of them. So yes, this is obviously cool stuff.

    • @JBaker452
      @JBaker452 7 ปีที่แล้ว +1

      As a refresher I should talk about Q again. Basically, so we all know what I'm talking about. So.. decades ago a collage professor exposed me to this idea, that there was a function than looked like this: Q(n) = Q[n - Q(n -1)] + Q[n - Q(n -2)]. And for tiny n, Q(n) = 1 so it bottoms out. This becomes the beginning of the problem 'doesn't it'

    • @JBaker452
      @JBaker452 7 ปีที่แล้ว +1

      So these deep recurse functions are basaltic non polynomial.

    • @drpeyam
      @drpeyam  7 ปีที่แล้ว +2

      Marcus Laurel It's basically an application of epsilon and delta, if you're still interested in seeing it!

    • @drpeyam
      @drpeyam  7 ปีที่แล้ว +3

      Marcus Laurel Here's the idea, although this proofs needs a tiny modification.
      Step 1: Let L be the limit of f (and h).
      This means that for all e > 0 there exists d > 0 such that if |x - a| < d then |f(x) - L| < e. But by definition of absolute value this is equivalent to saying -e < f(x) - L < e. Similarly we have -e < h(x) - L < e.
      Step 2: But then since f(x)

    Yes know this one, good for checking continuïty of multivariable functions like xy^3/(x^2+y^4) in (0,0). Also can you please show the steps for or do a video about lim x to 0 of (1-cos^3(2x))/x^2? Didn't have enough time to get to the answer on that one today :p.(without l'hopital)

    Theorem about the tight limit or clenched the limit? This is a lemma about two cops! This name is very frequently on the internet in Czech language, mainly on Mathematic and Physical Faculty. When two cops lead the prizoner, he goes in that direction as cops.👮👤👮. But I have read, somebody said in on the exam on Technic Univerzity, there was the problem.😊

  • @mertaliyigit3288

    Can this be used in complex plane as well? I know inequalities doesnt work on complex variables, but squeezing functions still seems possible

    • @drpeyam
      @drpeyam  2 ปีที่แล้ว +1

      You can put absolute values and then use squeeze theorem, that’s the only way

    Can we say the sharp point where tangent line does not exist but concavity changes as point of inflection?

      I’d call it that!
