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.
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.
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.
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.
Best video I’ve ever seen in my life 👍👍👍🚨🚨🚨🏃🏃🏃💨💨💨
Best math teacher ever!!!! (W Mrs. Park)
Better than Khan Academy! thank you, Ms.Park!
Woahh
Why is it 360 and not 2pi for the k value?
Very helpful! Thanks Ms Park
Thanks. From Bangladesh.
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!

I know, and I'm sorry. It's part of the "charm"? Glad you found it helpful anyway. :)

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.
very helpful thank you!

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?

@@lightblade4447 Thank you. Although I've already found the answer, but this is helpful.
@@lightblade4447it did even help me thanks
Nooo way.........I was just working on the wp and 13:40
First

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.
This is terrible
it is good

I must disagree, Austin.
I think This is a fantastic video
