Symbolic Computation

Definition

Symbolic manipulation refers to the process of manipulating mathematical symbols and expressions to perform operations such as simplification, differentiation, integration, and solving equations. This technique is central to symbolic computation, as it allows for the exact representation and transformation of mathematical entities rather than relying solely on numerical approximations. It plays a crucial role in various applications, including computer algebra systems and interfacing with other software tools, making it essential for efficient problem-solving in mathematics and engineering.
