Trigonometric functions giving you trouble? Check out DeadLine, a free program for solving equations and finding their derivatives, integrals, and min and max points. Just enter a formula to have Deadline instantly graph it.

You can add parameters, save graphs in the most popular graphics formats, and store roots in an HTML file. The buttonless scientific calculator looks a bit strange, but thanks to drop-down menus it's very convenient for entering long, complicated formulas. What's more, you can add your own constants and functions (although, unfortunately, you can't save them between sessions).

DeadLine occasionally crashed when we were solving sophisticated equations, but it should be adequate for basic calculus and engineering courses.

## Developer's Description

DeadLine is a program useful for solving equations, plotting graphs and obtaining an in-depth analysis of a function. Designed especially for students and engineers, it combines graph plotting with advanced numerical calculus, in a very intuitive approach. Most equations are supported, including algebraic equations, trigonometric equations, exponential equations, parametric equations. DeadLine solves equations graphically and numerically. It displays the graph of the function and a list of the real roots of the equation. You can evaluate the function and the first two derivatives, find extreme of the function and integrate numerically. Save the results provided by DeadLine so you can easily integrate in your school projects. While there is no flawless method for solving equations, the program combines the most successful methods in order to deliver you the right answer.
