The Graph of The Sine Function

[Europe1993]

Cant you just do : f(x)=sin x

and explain mathematics behind it ?

[Samuraikidd271]

Wait, aren't you supposed to use period/4 for the intervals?

[sarawrkang]

please be my math teacher. please.

[dyonnegalata]

WHAT HAPPENED TO PIE/4?

[PotatoeSmiley]

yaay! i know it now

[KCAASE]

This is the best conceptual explanation I have ever watched. Thank you. Now I understand why the sine function is the way it looks in the book.

[737FSPilot]

Thank you this helped a lot!

[amethystamg]

Fabulous video- I FINALLY GET IT! Your graphics and explanation were perfect. I feel so much better prepared for calc next semester. Thanks, Walt!

[ladiferente666]

Can't stand the voice...need the help though. lol

[Supernova12034]

Can you not use radians? @_@ and use degrees instead?

[Gordonverno]

@Supernova12034 I think thats just basic form for how its done, because its referring to a different spot in the unit circle.

[xa0wnerx]

calculus,precalculs, trig all suck balls

[kurankaname111]

@xa0wnerx im a fourteen year old guy., i studied this last year,

im a filipino

middle school/ highschool

its hard for our age and we are in the star section

[kayrod86]

Awesome explanation and graphics to go along.. Not everyone learns the same and I learn by watching and finding the logic behind formulas and how they relate to previous material. Definitely wish u were my prof too. :D

[legna28]

My precalc teacehr is a beach. I wish she was like you.

[joesjoes20]

would have been helpfull to have an example equation like for example: y=5sin2(X-35) +17. And for you to take an example equation and show step by step on how you would graph it. Because THAT is the kinda stuff i need help with >.<

[xastrickxplusx]

why didnt you use pi/4??? i wish you were my teacher btw... he sucks .__.

[rosslahive]

thanks mate this helps a lot :)

[kar453]

i think it's okay if y=sinx but it gets slightly confusing when there are coefficients added or if it's y=sin (x+b) or something like that.

[Smashbrosmojo]

Teacher Walt, do u speak Sine Language?

[meloveknit]

I'm pretty sure he does >.>

[Zmuslim]

Thank God! thatnk you so so much. that has helped me a lot.Awesome teacher!

[312527Lou]

VERY Helpful! :D

[Scorpioliciousful]

Thank you so much! I had to write an essay on this and I had no idea what to say!

[greencoveredbridge]

This is a GREAT explanation. Thank you so much.

[vfernandez92]

wow this helped me so much!

[10tailedjinchurikki]

Maybe if my teacher taught this way Id get this.

[monoukotori]

Thats one of the best explanations ive seen. if the teachers explained it that way when i was in school i might not have had to study so much

[longz654321]

so do you always use these angles to graph sine function?

[TeacherWalt]

Yes. Multiples of Pi/6 are the easiest to use. So I always use these when I want a quick sketch.

[shinyjewelsz]

Beautifully taught. Now i know the concept behind these trigonometric graphs! It makes sense.
