Practice using the sum formula for tangent given various bits of information about the two angles in the sum. I make a careless mistake early on, miscopying a 7 as a 2.

I point out the error on the screen; you can choose to either just read through the handout or watch the remaining part of ...

    Hmm, I think I know what I'm looking at. I think you just up'd my game. How come your spirals don't hit the center then veer off to the right with a squiggle? Sorry, bad terminology. I'm not in your class. I'm just a loser bum, not a mathematician. I took a linear algebra class and dropped out. I think we are in the same ballpark though, but our functions are a bit different. So, the quadratics are two axes of rotations. They can make a sink or a 3d wave. Cubic's have three axes of rotations. So on and so forth. I imagine these all make Rhume Lines when projected onto spheres.

    U should author a book on Calculus with many examples of ε δ limit proofs, u explained it so well. U are blessed with a brilliant mind. U left no doubt in my mind about even the smallest things. For the first time my mind is accepting with clarity every aspect in the solution around ε δ proof from the beginning to the end. Thank you so much

    What I think is kind of sketchy about these epsilon - delta proofs is the need to 'pre-suppose' what we are trying to prove in order to find a value or set of values for the variable 'delta'. It REALLY seems like some-sort of circular logic. Pre-supposing that 'idea', for lack of a better term, then demonstrating it works in the other direction (essentially just substituting it back into the proof, just 'undoing' all the algebra we did to find it), just seems like circular - logic. We learn these proofs in calculus one, see them maybe on the corresponding midterms / the final exam, and BAM never seen again. These proofs are just a logic fallacy, and a waste of time and brain power.

    Anyone know why we have to bound delta to be less than one, why not some other number.

    • @ScytheCurie
      @ScytheCurie Рік тому

      We often use 1 because it makes the math easy, but you can choose any positive number like 1, pi, 1/e, 52!, etc.

    • @ChimezieFredAnaekwe
      @ChimezieFredAnaekwe Рік тому

      ​@@ScytheCuriethe whole essence of limits is to come closer as possible therefore 2+ delta is good estimate. Also remember that the goal of the proof is to determine that the limit exists at x = 2 and that it is actually 4. So delta must be close enough to 2
