Calculus 1.3b: Lines, Parabolas, Circles, and Translations

[bebeheuy]

I am very happy to see the vidoe after you give this The second part to the lecture.

[AntoMelta]

I Really Like The Video From Your Lines, Parabolas, Circles, and Translations

[willamricard]

Your Video Is Very Useful Sharing The second part to the lecture.

[imegatrone]

after i watched this video, my insight is very open because the video is very good to give information The second part to the lecture

[damnitslukky]

You're confusing me, when you're talking about circles the K value was the radius or the diameter? I am familiar with the translation principle. I am taking precalculus next year and then calculus.

[kdum8]

Quick question. When translating the circle in the positive x direction (right) why is it (x-k) and not (x+k)? Surely you would require a positive number to shift it to the right and a negative number to shift it to the left? Great videos by the way, thanks.

[dbassett74]

Ya, I don't get that either. Shouldn't it be + to move to the right or up, and - to move left or down??

[lovelivelifewthrocky]

heeelp i dont get it but yet again im only in 8th grade, take it easy

[zstickey159]

ummm why are you trying to do this math in grade 8 if you dont get it when u ussually dont have to know it till like later on in high school...im in grade 7 and I just finished studying trigonometry but i get it....my advice to you is dont try to do this untill you have pretty good knowlege of both algebra and trigonometry

[Love2Bpretty]

can u please make a vid on how to tell when a graph is contineous? and when its differentiable stuffs like that?

[k1ngross]

Another nice video thanks...suggestion though... "All these terms get...." NEGATED!!

[soccerfan113]

good lesson i already know all this but now i understand more of the logic that drives some of the equations

[bradkey98765]

hmm farly simmilar to what i did on my own yesturday. I was trying to make the formula for a circle and ended up with y=±(r^2-(x-a)^2)^(1/2)+b when a=x coord of the origin and b= the y coord.

[flobber238]

Take it easy.

[flipponzin24]

I cannot thank you enough for helping me awakening the skills that I somehow lost after Pre-Calculus. You're work is great.

[ydultm]

wat the hell... crappy drawing??? that was like the best drawing ever... my paroblas look like crap and i cant even make a straight line >.<... anyways great vid

[bencorgan]

You waste so much paper! and you hold your pen rather strangely although your writing is quite neat.

[pokemastermike]

You shouldn't rush. Quadratic equations need more attention! You didn't even give the formula X(subset1,2)=-b+/SQRT(b^2-4ac)­/2a

[smartissexy]

Indeed the quadratic formula is important, I may even spend a video deriving it. However, I'm assuming calculus students have taken a solid background in algebra and precalculus, and thus have encountered said formula. Besides, solving the quadratic is not so important in terms of the calculus we can do on quadratics (or polynomials in general).

[bencorgan]

yeah you're right.

[joshnghiem]

lol your left handed :D
