What is the x axis of a sine wave?
The x axis indicates time in seconds; the y axis, relative intensity in arbitrary units. The number of repeated oscillations per unit time indicates the frequency, measured in Hertz (abbreviated Hz). The arrow points to where the oscillation repeats itself at .
Where does a sine graph cross the X axis?
Notice on the graph y = sin x, the graph passes through the origin (0,0). Then the graph crosses the x-axis at (p,0). When we make c positive, we move the graph to the left c units.
What are the 5 key points when you graph the sine function?
They are the three x-intercepts, the maximum point, and the minimum point. All of these are on your unit circle. The values of sin x correspond to the y-values, so those key points are (angle, y-value) or (0,0), (π/2, 1), (π, 0), (3π/2, -1), (2π, 0).
How do you find the equation of a graph?
To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.
How to plot a sine wave using matplotlib?
Using the numpy sin () function and the matplotlib plot ()a sine wave can be drawn. # Plot a sine wave using time and amplitude obtained for the sine wave
How to create a sine wave graph in MATLAB?
MATLAB incorporates the flexibility of customizing the sine wave graph. It can be achieved by editing the attributes for plot () function. xlabel: x-axis label is generated. Ylabel: y-axis label is generated. Axis square: It enables the user to generate the sine wave in square form.
What does the Y axis of a sine curve represent?
The Y-axis of the sine curve represents the amplitude of the sine wave. The amplitude of the sine wave at any point in Y is proportional to the sine of a variable. The sine curve goes through origin.
What kind of curve is a sine wave?
The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called ‘sinusoidal’ after the name of the sine function. This shape is also called a sine wave, especially when it appears in radio and electronic circuits.
