Mathcad enables engineers to easily perform, document and share calculation and design results. Mathcad’s interface accepts and displays units aware math notation using keystrokes or menu palette clicks with no programming required. What sets Mathcad apart is that it’s easy-to-use. In fact, it’s the first solution to enable users to simultaneously solve and document engineering calculations in a single reusable worksheet, which can be saved or easily converted to several formats. Mathcad’s intuitive interface combines live, standard math notation, text and graphs, in a presentable format which enables knowledge capture, reuse and design verification for improved product quality.
