word problem Trigonometry
Hello, me again! and I need ur help!
In summary octupus ride
one revolution=60 seconds
max 4m above ground
min 1 m above ground
h in metres above ground can be modelled by
h=asin (kt) +c where t=time in seconds
what is the desired period of the fxn?
my answer: I just assumed its 60 seconds? am I right
Determin the value of K that results in the period desired
so for amplitude I got 3/2 and vertical translation 5/2
h=3/2 sink (60) +5/2
im stuck. I have have no idea how to solve for K, since there is two varialble. any hints is appreciated!
