how do i lock in? ;-;
Best video I’ve ever seen in my life 👍👍👍🚨🚨🚨🏃🏃🏃💨💨💨
Why is it 360 and not 2pi for the k value?
Best math teacher ever!!!! (W Mrs. Park)
Not sure if this is still an issue but the audio transitions between the speaking audio and the music audio is an order or 2 of magnitude higher and blew my speakers, just saying. Everything else is spot on.
I know, and I'm sorry. It's part of the "charm"? Glad you found it helpful anyway. :)
Just learned a whole months worth of work in 20 mins 😅
How do you determine the value of K if only given the maximum and minimum?
Sorry this is old and you probably already got an answer, but if the distance between a max and a max, or a min and a min, is a full period. That means that the distance between any given max and min points that are next to each other should constitute half a period. As such, you just have to double that in order to get the period. The k-value can then be found using the 360/period.
@@lightblade4447 Thank you. Although I've already found the answer, but this is helpful.
@@lightblade4447it did even help me thanks

Thanks. From Bangladesh.
Awesome video! Thank you, Ms. Park!
Better than Khan Academy! thank you, Ms.Park!
Woahh
very helpful thank you!
Nooo way.........I was just working on the wp and 13:40
Galing nyo po thanks for sharing
This is terrible
it is good
🤡

I must disagree, Austin.
I think This is a fantastic video
helpful.
Why do you divide 360 by the period while in other problems I've seen this: period = 2pi/b? Is there a general rule for when to use either of these? Does the type of problem determine the method? I get that 2pi = 360, but the subsequent values are not equal.
I am not sure what you mean by "b"? The number in the denominator is the number of cycles in 360 degrees (or 2 pi). For example if the denominator is 5 then that means 5 cycles take up 360, so each cycle is 72.
isn't it cosign for the 3rd one
I mean the one at 13;58
Can be either sine or cosine - depends where you start your cycle.
I really appreciate this video. Very instructive. At 14:52 I suppose the equation could also be expressed as y = - 0.3 cos (144t) +1.8?
Correct!
Thank you for posting. Please clarify at 2:04 you indicate the PS as 30. I was previously instructed that it was calculated by c/b which would be 30/3 in this example making the PS 10. I'm confused.
Joe, if it was 3t-30 instead of 3(t-30), then you would factor out the 3 and the phase shift would be 10.
Where do you get these worksheets?
Very helpful! Thanks Ms Park
First
True. 4(19)+4 is not 70... but you get the idea! :)
😄 Hi Ms Park!
I think you got example 6 wrong t19 should be 80, not 70
doesn't t19 euqal to 80?
Lit
For good communication hahahha~~
Love to use guess and check hah~
Good old guess and check...
looks great!! hah ~~
