DeadLine screenshots
Enter the equation, the interval where you want to solve it and the parameters if you want solve parametric equations. Starting with DeadLine 2.30, you can preview the graph in DeadLine Wizard, so you can tweak the interval and the parameters faster.
DeadLine automatically displays the real roots of the equation in a scrollable list. To locate a root on the graph, select it from the list.
Graphs can help you locate the intervals that contain roots. Once you know where to search for the roots, DeadLine finds them for you. You can also solve parametric equations.
Plot graphs in fullscreen view, zoom in and zoom out, change the interval, customize the colors and save the graphs.
Integrate a function numerically. The graph is shaded to better visualize the selected area.
DeadLine saves the most recently used equations. To reopen an equation, select the name from the list or type the first characters.
