In summary, the conversation discusses the task of calculating the lengths of horizontal and vertical timber supports for a roller coaster track in the shape of a sinusoid. The track has a horizontal separation of 50 meters and a vertical separation of 30 meters with the low point being 3 meters below ground. The problem asks for an equation expressing the vertical distance, y, in terms of the horizontal distance, x, using the standard form of a sinusoidal equation. The user has drawn a sketch of the graph and is seeking help in determining the values for a, b, c, and d in the equation.

A portion of a roller coaster track is to built in the shape of a sinusoid. You have been hired to calculate the lengths of the horizontal and vertical timber supports to be used. The high and low points on the track are separated by 50 meters horizontally and by 30 meters vertically. The low point is 3 meters below ground. Let y be the number of meters the track is above the ground and x be the number of meters horizontally from the high point, write an equation expressing y in terms of x.

Hello and welcome to MHB, jenherting! :D

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?

So far the work that I have was I drew a sketch of the graph itself and now I just need help on how to write the equation and what parts of the problem represents the aspects of a sinusoidal equation.

This seems odd. Are you sure it's not 3 meters above the ground?

You need an equation of the form

$$y=a\sin(bx+c)+d$$

Any thoughts on where to begin?
