Fairly new here but here is the best way to understand this so far. Watch in order: 1. JG’s video on Angles in standard position 2. JG’s video on Radians and degrees 3. JG’s video on the Unit circle 4. Now you can finally understand this video

Eh bruh work on your study schedule, you just cannot study before an exam rather revise and SLEEP.

[@rubyjane9608]

I need to know what was your grade

[@hanadalishidane7808]

Best teacher, Hands down

[@jackcoleman5248]

you forgot how to show us how u got those values from the angles given. that is what i was looking for and you just skipped over it

[@Sky-yy8bg]

Try to draw a line from the vector over any point on the circumference and measure it with an angle ruler. I think that's the only way you'll find out the angle

[@Sky-yy8bg]

You can also find the angle if the radius has a given value, let's say we have 6cm, and we where given an arc length of 12cm in the circumference... Ø=S/R which Ø=12/6.. then Ø=2rad. Or 2 radians.. 1 radians is equal to 57.3 so 57.3 • 2 will be 114.6°.

Dude, cosθ=x & sinθ=y. Please consider revising, as this is a misleading thumbnail and will mislead students...

No, it's not you are a full-grown woman/man so study and practise and try to understand and ask questions where you don't understand.

[@jeevanpena9473]

There's no explanation how do √3/2 and 1/2 exist. It really confuses me huhu. 1:31

[@thepathlesstraveled659]

Watch Unit circle video you will understand.

[@abhirams3057]

From where did, divided by 2 came in 0:57 while taking coordinates

[@javierjb8658]

lookup the unit circle and it breaks it down for you but it comes from the Pythagorean Identity (cos^2 t+sin^2 t=1). when you break it down and determine what quadrant it falls under you'll know if it's a positive or negative coming out of the square root.

[@brentcasas4898]

I will just accept the fact that I watched a tons of videos about this topic. but still can't understand it, I moving to accept that I will fail my exam.😆

[@4nomenalstyles]

this is very very sad Mr/Ms Brent, how was the exam?

[@St.Raptor]

Same dude. I'm terrified. I'm wasting my money and time here at college.

[@m870time6]

The thumbnail for this video is wrong and contradicts what they said

[@-Quasar-]

the only thing wrong in the thumbnail is the x and the y, they’re flipped. Not that big of a difference

[@calvinwitt955]

lost a few points on quizzes because of this thumbnail, their chemistry videos are pretty good though

[@Tanrdsgener]

It's clearly clickbait, guys.

[@jonwilliams6703]

Should probably explain wh sin and cos are only x and y

[@arnold-io2zx]

SOH CAH TOA,, SOH SINTHETA)=OPP(Y)/HYP(1) we all know that divide any number to one is same as numerator so thats why sin=y,, same us cos=x

[@sanopann1896]

the only way to help this guy back is to watch the ads that popping out on his video and I'm going to write this comment to all of his video for you to know you can help him back by just watching his ads

[@wengeance8962]

How do you find the 'point' you describe at 0:48?

[@emeree]

study.com/cimages/multimages/16/imagetrigfunctions9.jpg ^ That's a table describing the value of each trig function when special angles (e.g. 30°, 45°, 60°, etc.) are involved. Mostly you just need to memorize these values, even though it's a pain to recite, but it is helpful. Anyway, in the video you learnt: sinθ = y cosθ = x you know that θ is 30°, so you substitute it into those equations: sin(30°) = x cos(30°) = y then you just consult that table and you get the values of x and y, and hence you know P(x,y) is exactly the value shown in the video. if you want to learn in detail about the reason behind those special values, I recommend this video: www.khanacademy.org/math/algebra2/trig-functions/trig-values-special-angles-alg2/v/solving-triangle-unit-circle Hope this helped! it's been a year since you asked but hopefully this helped other people too :)
