Example: Graph, domain, and range of sine function | Trigonometry | Khan Academy

[@jonathanmcdonnell7238]

Thank you so much! This topic came up in a book i was reading and when i asked others for help they just said that it was too complicated. Your video was extremely helpful, thorough, and simple. Thank you very much!!

How did it go?

@@giljorge7479 I can’t remember but I’m studying philosophy now so it can’t have been great

@@Mary-eo7ir what are your thoughts about philosophy

ive learned this when i was in high school but completely forgot. so i need to revise for my uni XD

Hi Sal how do we determine the domain and range when doing sine functions? It’s easy in algebra but it’s my first time doing geometry and trigonometry.

when mr. jumash brings you here 😳😳😳

wow

[@shujatalikhan6582]

Someone told me that Domain of sin x is from 0 to 2π. How's that possible?

[@craigpointon8394]

because that is the length of the unit circle

[@isavenewspapers8890]

That's not actually true. sin(x) can have inputs less than 0, and it can also have inputs greater than 2π.

[@zdrzzyz6019]

why are we making up words like Theta? why not just call it Data? Just simple things that make this math even more complicated

[@krszkkn]

we are not making the word theta it is just a variable like other variables like x,y,z,a,b,c,etc but it is just reserved for angles

[@martinbartsch7619]

mr. weber brought me here

[@swatisahiba5096]

The way he pronounces theta is deadly for Indians.🤣🤣

[@bajodah1847]

What is this? 😔

[@calebrossouw9060]

Can you stop using π please 😂😂

[@isavenewspapers8890]

So are you saying to use τ, or not to use radians, or what?

When you have a math problem. Better call Sal.
