Amusement Rides A proud father is attempting to take a picture of his daughters while they are riding on a merry-go-round. Horses on this particular ride move up and down as the ride progresses according to the function $$h(t)=\sin \left(\frac{t}{\pi}-2\right)+4$$ where $h(t)$ represents the height (in feet) of the horse's nose at time $t,$ relative to the merry-go-round platform. However, because of safety fencing surrounding the ride, it is only possible to get a good picture when the height of the horse's nose is between 3.5 and 4 ft off the merry-go-round platform. Find the first time interval that the father has to take the picture.

Key Concepts

Trigonometric Inequalities

Solving trigonometric inequalities involves finding the set of input values that cause the trigonometric function to yield outputs within a specified range. This is essential when determining intervals during which a cyclic event, such as the height of a ride, meets a particular condition.

Inverse Trigonometric Functions

Inverse trigonometric functions are used to determine the angles corresponding to specific trigonometric values. They are a key tool when solving equations or inequalities where the goal is to identify the precise points in time or angle measures that satisfy a given condition.

Trigonometric Functions

Trigonometric functions, such as the sine function, are used to model periodic behavior and oscillatory motion. They exhibit properties like amplitude, period, and phase shift, which help describe the cyclical variation seen in many real-world phenomena.

Function Transformations

Function transformations involve shifting, stretching, compressing, or reflecting the graph of a basic function. This concept is critical when analyzing how the sine function in a model is modified to fit a particular scenario by incorporating horizontal shifts and vertical translations.
