How to Find a Sine and Cosine Curve's Equation - y=a.sin(bx)+c, y=a.cos(bx)+c - Lesson & Examples 1

In this video we learn how to find the equation of a sine curve and a cosine curve from its graph.
We learn and use the formula for :
- the Amplitude
- the Wave Number (also called Angular frequency), which is inversely proportional to the period
- the vertical translation.
These trigonometric functions will be easy to tackle after we've watched this tutorial.
