A print out of the graph obtained in Desmos showing the lateral view

A print out of the graph obtained in Desmos; showing the lateral view of the roller coaster track and the equations, on the left hand side, that were used. It might be better to take a screenshot.

A short paragraph describing the process I went through to design my roller coaster track: I started by sketching the basic shape of the roller coaster, considering the different sections such as slopes, peaks, and valleys. I then translated these sections into mathematical equations, primarily using piecewise functions to model each part of the track accurately. I entered these equations into Desmos to visualize the track from a lateral view, adjusting the parameters to ensure smooth transitions between sections. I used the graphing tool to refine the shape, ensuring it resembled a realistic roller coaster layout while also satisfying the mathematical criteria for continuous and differentiable functions.

Answers to the following questions

  1. What does the domain of your piecewise defined function represent?
  2. The domain of my piecewise defined function represents the horizontal extent of the roller coaster track, indicating the specific interval over which the track exists from start to end. It shows the set of all possible x-values corresponding to positions along the length of the roller coaster, from the initial ascent to the final descent.
  3. What does the range of your piecewise defined function represent?
  4. The range of the function represents the vertical heights of the roller coaster at different points along the track. It illustrates the elevation profile, including the peaks (highest points), valleys (lowest points), and intermediate elevations, reflecting the roller coaster’s elevation changes from start to finish.
  5. Does your function have relative or absolute maximum or minimum values? At which values of x do they occur? What do they represent?
  6. Yes, the function has both relative and absolute maxima and minima. The absolute maximum occurs at the highest point of the initial peak, where the roller coaster reaches its highest elevation before descending. Relative maxima may occur at other peaks along the track, representing potential highest points within specific sections. The minima occur at the lowest points, such as the bottom of valleys or dips in the track, representing the lowest elevations. These points are critical for designing thrilling and safe roller coaster rides, as they indicate the sharpest upward and downward swings in the track.
  7. Can your roller coaster have loops? Why?
  8. Under the current design using the existing equations, the roller coaster cannot have loops because the functions modeled do not include the necessary vertical circular paths that define loops. To incorporate loops, the mathematical model would need to include parametric or circle-based functions that define a continuous, smooth circular trajectory, ensuring that the track can realistically and safely pass through the loop without discontinuities or unrealistic sharp turns.
  9. What would you do to add a loop to your roller coaster? Can this new roller coaster be represented by a function?
  10. To add a loop, I would incorporate a parametric equation representing a circle or an ellipse into the existing model. This would involve defining x and y coordinates that create a circular path, ensuring the loop seamlessly connects with the adjoining sections of the track. It is possible to represent the entire roller coaster, including the loop, as a single parametric function, because parametric equations allow modeling complex curves like circles and loops that cannot be represented as single-valued functions of x alone. This approach ensures continuity, smoothness, and the physical feasibility of the roller coaster design.
