This project developed an app which allows the user to explore Sinusoidal Wave plotting by varying four parameters. The rest of this presentation sets out how to use the app.

The app is produced using R Shiny and is hosted here: https://chrisn267.shinyapps.io/sinusoidal_waves

This work was produced by Chris Nightingale as the final submission for Developing Data Products - the ninth module in the John Hopkins University Data Science Specialisation.

A Sinusoidal (Sine) Wave takes the following form:

y = Amp * sin(Freq (x - PS)) + VS

where:

• Amp = Amplitude, the height of the wave
• Freq = Frequency, the number of waves in a period
• PS = Phase Shift, a right/left shift of a wave phase
• VS = Vertical Shift, an up/down shift of the wave

In this application this gets plotted as below (note that phasing is in degrees rather than radians).
