    Graph
In summary, the conversation is about finding the area below a graph in a shaded region. The person asking the question is seeking a definite answer and advice on how to use a calculator. The other person has given a hint to think about using trapezoids and estimating the area using squares.

Okay, so my question is: given the picture below, how can I find the area below the graph (in the shaded region) ? It's for a lab that I did in class, but it wasn't until i finished the whole picture that i realized that I didn't know how to calculate the area of this graph.

Thanks.

HINT: Think trapezoids! :)

If an estimate is good enough, just notice that each square represents 0.16*1 Nm = 0.16 Joules. Then just add up the squares and estimate for the non-complete squares.

at this point, i really need a definite answer ASAP, perhaps u can teach me how to use a calculator?

Perhaps I am reading this wrong!

You have been given some very sound advise in this thread already. Why don't you show us some effort on your part.
 

FAQ: Calculating the Area Under a Graph | Find the Shaded Region on a Lab Image

What is a graph?

A graph is a visual representation of mathematical data, typically consisting of points connected by lines or curves.

How do I create a graph?

To create a graph, you will need to collect data and input it into a graphing software or program. This can be done manually or by using a spreadsheet program like Microsoft Excel.

What are the different types of graphs?

There are several types of graphs, including line graphs, bar graphs, pie charts, scatter plots, and histograms, each used for different types of data and purposes.

How do I interpret a graph?

To interpret a graph, you will need to understand the data being represented and the type of graph being used. Generally, the axes of the graph represent different variables, and the data points or bars on the graph represent the values of those variables.

Can I customize a graph?

Yes, most graphing software or programs allow you to customize the appearance of your graph, including the colors, labels, and axes. This can help make your graph more visually appealing and easier to understand.
