Calculus and Symbolic Manipulation
Integration
You can calculate symbolic integrals for expressions with known
antiderivatives (indefinite integrals). You can also estimate the
numeric value of those and other integrals.
Numeric Integration
Numeric integration lets you approximate a definite integral—
even when symbolic integration can’t generate a closed-form result.
Numeric integration employs an iterative numeric procedure to obtain
the approximation.
