So the H(t) function is this
\[\Large H(t) = 20\cos\left(\frac{1}{15}t+30\right)\]
right?

Yea solved it and got 50. Is that correct?

so the +30 is definitely inside the parenthesis and not outside?

\[H(t)=20 \cos \left( \frac{ π }{ 15 }t \right)+30\] that's the equation

oh ok

So yes, plugging in t = 0 gives 50 as the output

at t = 0 seconds, he is at a height of 50 ft

Okay, what exactly do I do for the second part? That part confuses me

So it would be \[\frac{ 2π }{ \left( \frac{ π }{ 15 } \right) }\]

yes, simplify that fraction

We can take out the pi's right? so we would now have \[\frac{ 2 }{ 15 }\]

Ohh \[\frac{ 30π }{ 1π }\] ?

and the pi's will cancel

Okay thank you :) I'll try and see if I can get part three on my own and if not I'll let you know :)

alright

Okay I'm confused as to what the question is asking exactly

|dw:1433458814224:dw|

how long does it take to go around the full circle?

30 seconds

so how long does it take to go from the very top, to the very bottom?

15 seconds

plug in t = 15 and tell me what you get

I get a decimal when I plug it into my calculator
92.83185307

make sure you are in radian mode

Wait

so you'll have 20*cos(pi) + 30 = ???

I get 49.9?

you should find cos(pi) = -1
try again

10?

yep 10

yep the lowest it goes is 10 ft off the ground

Thank you :)

you're welcome
