Ferris Wheel Trig Problem

Three revolutions per minute! Dayum!

Your comment made staying up worth it, oml XD

Thats what I said!!! Puke City!!

[@anthonycapalot9587]

It is a relatively small Ferris wheel, so if you think about it, it isn't horribly fast

[@danielt7165]

Sheeeeeeeesh

[@samisabbah52]

You made it more confusing...

[@atmajp9275]

bruh, what all of these comments are saying he made it more confusing.. i havent even learnt trig in my school and i completely understood it

[@nuffinmuffin7351]

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

[@shunngillies5185]

Bro your comment was 12 years ago, are you still there?

[@kosterot]

WHY ARE YOU MAKIN SO COMPICATED JESUS

[@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.

weeee, it totally makes sense. Tks a lot. At school, I nearly just remember where to put a,b,c,d in h = a sin(b(x-c)) +d. now I understand thoughtfully

[@KS-bo6tq]

ok but why did they need to specify it was in Montana

this was posted on my 4th birthday

[@ihavetodomyhomework]

I love this guy.

[@bigdude1995]

meh, i used sine instead... h=8sin(18t-90)+9 when t=seconds

[@atmajp9275]

nice thats actually pretty cool

[@ahmedatifabrar7698]

Better resolution?

[@Killdeer101]

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

[@apestogetherstrong341]

Isn't the simpler solution h(t) = (1 + sin (18 t)) * 8 + 1 ? From the unit circle we know that sin of a degree is the y coordinate. Sine goes from -1 to 1, so 1 + sin is gonna give a variation from 0 to 2. Then, if we multiply the sine result by 8, we move from the unit circle to the 8m radius circle, and we get the height in terms of this circle, where the lowest point is 0 and the highest is 16m. Then we add 1 since the wheel is 1 meter above the ground, and we get the height of the users as a function of time. on the ferris wheel (knowing the starting point 0 to be at 9 meters above the ground, or at 0 degrees relative to the ferris wheel center)

[@MohamedHassan-jt4wy]

you made all of that based on a construction of a degree at which 9-h but if you raise the construction you will find that h-9 is the number which appears

[@chittaphrrr3547]

Thank you !!! You're a lifesaver!!!

[@kishaschannel8081]

Khat thank you

[@Killdeer101]

never mind you included the 1m from the ground.

[@ReaverKS]

Thank you very much for making this video

[@tulsikiran661]

helped me a lot thanks!

[@wskinternational3131]

Wait...What happens to the (9-h) side when h >= 9? Does the solution still work or do we need to modify it?

[@jonathanpettersson3421]

in that case cos (18t) will be negative, so the negative cancels out.

[@Craftz16]

thanks for the help

[@lifeDotGov]

@louiseypoon do you know what sinusoidal functions are

[@SpartanGJ23]

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

[@kevivjun]

are u a math teacher?? ur really smart

I mean he is the host to one of the largest math learning websites/ youtube channels. So yes he is a math teacher of some sort.
