Elements of the theory of integers by Joseph Bowden

Show description

To continue, we select A2, we click and holding the mouse left button down, we drag the mouse down to A3 so that both these two cells are highlighted; then we release the mouse button. When properly done, A2 will have a white background but A3 will have a black background. We will now use the AutoFill* feature to fill−in the other values of x in Column A. 00. 05. Next, we select B1, and we type f(x). 00 . 000 . 00 Next, we want to copy this formula to the range B3:B102 (the colon : means B3 through B102).

We observe that after pressing the key, the next cell moves downwards to A2; this becomes the next selected cell. 00 in A2. We observe that this value is displayed just as 0, that is, without decimals. 05 in A3. We observe that this number is displayed exactly as it was typed. We will enter more values in column A, and to make all values look uniform, we click on letter A on top of column A. We observe that the entire column is now highlighted, that is, the background on the monitor has changed from white to black.

This command plots y versus x where x is the horizontal axis (abscissa), and y is the vertical axis (ordinate). • If a statement, or a row vector is too long to fit in one line, it can be continued to the next line by typing three or more periods, then pressing to start a new line, and continue to enter data. • We can make a two−dimensional plot more presentable with the commands grid, box, title(‘string’), xlabel(‘string’), and ylabel(‘string’). For a three−dimensional plot, we can also use the zlabel(‘string’) command.
