Ferris Wheel Trig Problem

[bigdude1995]

meh, i used sine instead...

h=8sin(18t-90)+9 when t=seconds

[Souriyy]

@bigdude1995

or 9 - 8sin(90-18t)

[louiseypoon]

SAL... IT ASKS FOR A SINUSOIDAL FUNCTION NOT A COSINE :S

[lifeDotGov]

@louiseypoon do you know what sinusoidal functions are

[nabeek999]

@louiseypoon sinusoidal means sin or cos :S

[SpartanGJ23]

if h=9, then shouldn't 9-h=0? anyone else notice that?

[louiseypoon]

@SpartanGJ23 He just named them both 'h'. They are two different things. Maybe he should have put H and L or something like that

jajaja-7:00 someone at the door for u sal or what?

[philwild12]

hey, I repeated this but for a clockwise rotation, any idea why the function has to change to a+bcos(speed x time) rather than a-bcos(speed x time)

WHY ARE YOU MAKIN SO COMPICATED JESUS

[bomrdude]

@kosterot I didn't know that Jesus taught math.

[EltBerserker]

Wow, i'm a math major but i totally forgot about trig since HS, this is amazing!

[91jgphonecall]

i cant make functions out of word problems. my math text is constantly asking me to make stupid functions. what the hell, how are peolpe suppose to do that. i think im missing a chromosome.

[aussieace450]

i had tp punch on with my brain towards the end there a little bit.. could feel it switching off... wish i could just be a natural genius

[TheEliteNinja]

wow he is a genius.

[62JAS]

can you do a video about the angle of elevation and depression?

[tenzinbee]

thanks alot that helps :) !!!

[nuffinmuffin]

you are my hero!!! we need more of you people around

[MuscularBeaverx]

this is the hardest trig problem by a long shot since it encompasses AV and trig.

[TheArtisticman]

this dude is smart

[xOxVampiresLiveInMeX]

i thaut it was a real proplem

[bigmac364]

Thanks dude you explain this way better than my book.

[Craftz16]

thanks for the help

[Killdeer101]

never mind you included the 1m from the ground.

[Killdeer101]

isnt h=8? cause thats the centre and the radius is 8 cm.

[Guiitaristt]

h is the height above the ground

the radius of the ferris wheel is 8m, and the wheel itself is 1m off of the ground.

[shortie0306]

thanks :D this helped me soo much

-tika

[ReaverKS]

Thank you very much for making this video

[NothingIsFact]

Wow. I was assigned this problem today in class, just with different values. This is a huge help.

[kevivjun]

are u a math teacher??

ur really smart

[cutegirl9163]

I'm not criticizing u or anything, but why did u make this video?

[MrSoada]

Because it helps. Ferris wheels pop up in many trig books, believe it or not

[genericvideo1]

Used the ferris wheel in class today, and he is a professional tutor
