An electrocardiogram is a graphical recording of the cardiac cycle produced by an electrocardiograph monitoring heart beats.
line graph
The main purpose of a line graph is to show changes and patterns in the changes
Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
line graph
You can graph the changes in pressure. Or you can separate the sound into frequencies, and graph those (by amplitude).
A line graph
A line graph or a bar graph.
A Cooling curve graph changes shape.
Turning points are the points at which a graph changes direction from increasing o decreasing or decreasing to increasing.
Trigonometry helps nurses read the heart beats on an EKG because an EKG shows the heartbeats in a graph.
A scatter graph. A line graph need not involve minute changes.
A line graph, not surprisingly!
