I like the idea that you just killed the proof by working through it and the tombstone is justified.
truu dat
Nice acedamy
Ws in the chat this shit fire bro still helping ppl out 13 years later!!
Thank you sir ❤
Dr Tisdell is there any way of integrating x^2 root under ax+b dx other than substitution method?I mean by Algebraic Manipulations?
why is the period 1? Why do you put 2L=2?
f(x) = f(x+2) = f(x+2L) by definition, so L=1
@@DrChrisTisdelldo you have an email?
Thank You So much

Was sent to this video by a Pikuma course on 3D graphics. This video did help, but I felt like there were several places where a bunch of steps were skipped, and it took me a bit to figure out the missing pieces. Also, the low framerate made things hard to follow at times. Not incredibly intuitive overall. Also, the thing about assuming that lambda is 1 at the end to "get rid of it" was a bit confusing. I suppose the point is that lambda can be whatever we want, and when we assume it's the scalar 1 (it is a scalar and not a vector, right?), then it makes the math easy. I suppose I'm on board with that (assuming I'm understanding it correctly), but confusing.
Thank you so much 😍👍
Thanks!! Great story clarified!!
MORE!!!
I would love to see a series from this guy in which he explores the general solvability of equations in terms of, encoding the (generally unexplored) concepts of Liouville, Hadamard, Niels Hendrik Abel, Dirichlet, Du Hammel, Galois, Existence & theory of Algebraically Closed/Solvable Differential Equations - IN EXTREME DEPTH
Make videos about constructible numbers and other mathematical objects also, like, the Euclidean geometry is always awesome, but go tangent, parallel & orthogonal in all directions, including theory of Liouville Hadamard Duhamel Wronskian general Solvability theory and expressible/Algebraic /Galois Theory & the Likes I would love to see a proper series in the direction one day Overall - learned a great deal from you my friend
Some of the best videos ever seen on this topic - friendly intro always!
Is there any particular rule to assume the function u=g(x/y)?
Chris you are one BAMF! such a groovy set. I was lucky enough to have you for MATH1131 a couple of years ago, thank you for being by far the most engaging lecturer I've had and for these epic tunes.
thanks <3
at 8:19, you use two different f's, tan(πx/4) and ax+b, in the same equation, is this correct?
f is piecewise defined, so you would expect different definitions depending on the domain.
Great video. wish all professors had a nice thick whiteboard pen like that, really neat
THank you quick and easy learning
Thanks a lot for helping me understand this method😁
Nicely done. However, please finish the job. You found the angle that is 1/3 that of the original angle, but for completeness you should go ahead and apply that to finish trisecting the original arc.
This is why he's the GOAT!!!🔥🔥
Wow😮, you upload this video before i start kindergarten and now i watch it for my first year in engineering college
This was extremely helpful, thank you very much.
I love Chris (aka G.O.A.T)
this was so understandable
Thank you
you can square both eurros and sum the squares then take square root of that square root of (1^2+2^2) will equal to (square root of 5 )% which is more accurate
God richly bless you
You didn't define the domain and co-domain. Could you please do that
An example would be R and R^2 👍
Wow you really replied after 11 years. So, since R^2 = C this proof also holds for komplex functions, right?
Still helping after 14 yrs ❤❤❤
Ive gotten 7 different Videos about drawing circles in a row, this is insanity.
Dear Dr Tisdell, I love you. Lab Test 2 could not have been any easier because of you!!
Thankssss very much sir
You're my hero Sir, o7
i love you chris boss
Add a comment...
Dear prof, u save my life.
Thanks
Thank you for the video, good luck bruh
I cannot understand why did you chose to differentiate at point "b" , it is better to chose an arbitrary point "x"
walla sah
you made it so easy dude
Thanks a lot sir
Subbed and greatly needed
Excellent intuitive proof!
