Hi, I really need help with this question
1) the water depth in a harber is 21m at hight tide, and 11m at low tide. One cycle is completed approximatly every 12h.
a) find an equation for the water depth as a function of the time, t hours, after low tide
b) Draw a graph 48h after low tide, witch occured at 14:00
y=asink(x-c)+d
Amplitude
a=21-11/2
a=5
K
p=2pi/k
12=2pi/k
k=2pi/12
k=pi/6
what about the c and the d??
and does anyone know of anygood software to graph trig functions?
Thanks
