how to plot a graph in excel with equation

The code that describes the decaying sine wave is s np.sin (np.pit)np.exp (-t0.05) which means sin (t) e (-t0. If you want to plot a quadratic with Excel you have to choose your #x# values carefully to try to include interesting points, such as, the vertex and the intercepts. Lets say we want to plot a sine wave that decays over time. My version of Excel is in Portuguese but in English doesn’t change a lot. In the formula bar (see the red arrow) you can see the form of the quadratic (accepted by Excel) and the corresponding calculated value.

In the above Picture you can see the graph and the two columns for #x# and for the quadratic (in this case I've chosen: #x^2+2x-4#). I've chosen points and smoothed lines from the boxes on the right of the chart window: You can now choose to plot only the points or lines and points. This is represented by the following icon (in the chart window): The right graph to use is the 'xy scatter'. Next I would select the two columns (highlighting them) and choose 'chart' from the menu 'insert'. I would start by choosing the first column of the spreadsheet for the values of #x# and the second for the correspondent calculated values of your quadratic.
