Now, first, let's open our ui.R file, so we can see what kind of UX we're working with and we can see, right now, we simply have a fluidPage, so one page, shown here. Let's open up our server.R file and see what we have. We have the minimum requirement for our Shiny app to work at Shiny server function. And now let's also open up curve-plot.R. This script file contains just one line using the function curve. I want to run this, so we can see what it does, so I'll run the first line of curve-plot.R and what I get sent to my plot tab is a really nice plot of X to the power of two, or X squared. We're going to build into our Shiny app the ability to change the value of the exponent in this function with a slider. So let's insert the slider into the ui of our app before we move any further.
