you don't know me. But I want to give you a hug. I understand it. Thank you so much. I love that you explain why everything on your graph is labelled how it is. Thank you

We would be happier if you could have written the second question completely with the parts. Thank you

When do you figure out if there is a phase shift or not?

How did you get inverse of Cos ( 4 / 30 ) with an answer of 97.66 ... when I put that into my calculator .. inverse of Cos ( 4 / 30 ) .. I got 82 . 3377 .. where am I going wrong ?
@madmaths7895
@madmaths7895 11 месяцев назад
It is because you are taking the cos inverse of negative 4/30. I forgot to write the negative in the next line. My bad. But the answer remains 97.66.

thanks very underrated! also on an exam u would likely be allowed to use a calc for finding height and specific time? right?
@madmaths7895
@madmaths7895 Месяц назад
Yes, usually you just use a calculator.

How did u get 36 as the vertical shift, wouldn’t it be 6 since that’s the initial starting point ?
@madmaths7895
@madmaths7895 7 месяцев назад
The vertical shift is the distance from the axis (or midline) to the x-axis. Not from the lowest point.

where did he get the 40 from when he was doing the feriis wheel last question
@madmaths7895
@madmaths7895 7 месяцев назад
I was just showing that you could be asked a follow-up question like "when is the height 40ft?" 40 would be given to you in the question.

The question did specify to use a sinusoidal function, so does not that imply using a transformation of h - sin(t)?
@madmaths7895
@madmaths7895 9 месяцев назад
Sinusoidal functions refer to both sine and cosine functions!
@syu8641

what about finding time of when you reach a specific height for 4,5,6th time for example?

How could you explain how to solve the first time equation
@user-wn1bm3rr6t

With no calculator
@madmaths7895
@madmaths7895 Год назад
That would require a calculator for most people, myself included.

aren't you supposed to use 2pi instead of 360
@rr.richie

thats what i thought
@VivoVadim
@VivoVadim Месяц назад
pi = 180, 2pi = 360 degrees. They're interchangable.
@JonathanMechery
@JonathanMechery Месяц назад
2pi is in radians, 360 is in degrees. He's currently using degrees.
