This webpage checks how well you understand sine curves, i.e. graphs of the trigonometric equation y = a*sin(bx)+c. The value of a is called the amplitude, b is related to the frequency (= number of times the wave goes upanddown over an interval of [0,1]), and c is a vertical shift. Below is a graph for specific values of a, b, c. Your aim is to find these values and plot the graph of the same function.
