"Mathcad 15.0 has had various symbolic calculation capabilities for a long time. These capabilities were absent in Mathcad Prime 1.0 but, we are happy to announce, they have been added back into the available mix of functionality for Mathcad Prime 2.0! This newly restored symbolic calculation capability in Mathcad Prime 2.0 integrates smoothly with numeric calculation, using patented integration technology. Often in math and engineering software, formulas must be altered before they can be applied to a specific case. Mathcad Prime 2.0’s symbolic calculation functionality automates this process for you and allows you to set up the right form of the formula before plugging in numbers.
Kent Pitman, the Software Development Manager at PTC who oversees work on the calculation engine for Mathcad, shared his views with me on four interesting aspects of symbolic calculation in Mathcad Prime 2.0: explicit evaluation, the unique integration between symbolic and numeric calculations, using Lagrange notation (F’) for derivatives, and Leibniz notation for derivatives."
