Software for engineering calculations

Mathcad Prime 1.0 engineering-calculation software has a tasked-based user interface, which helps users focus on solving complex engineering calculations rather than formatting design documents. An intuitive WYSIWYG editor lets users write equations in natural math notation. When coupled with best practices, Mathcad can also be a standard for engineering teams to capture and manage design history as intellectual property.
