Question 1104960: A skier leaves behind a trail, with two turns creating one cycle of the sinusoidal curve.
The skier makes a total of 10 turns over a 20 second interval. If the distance for a turn
to the left of right from the midline is 1.2 m, what could be a possible sinusoidal equation
that models the curve?

You can put this solution on YOUR website! A skier leaves behind a trail, with two turns creating one cycle of the sinusoidal curve.

-------
period = 2 sec/cycle
amplitude = 1.2 m
------
Form:: y = a*sin(bx)
Period = 2pi/b = pi
---
Amplitude = |a| = 1.2
-----
Equation:: y = 1.2*sin(pi*x)
