- NIntegral[ <Function>, <Start x-Value>, <End x-Value> ]
- Let a be the Start x-Value, b be the End x-Value and f the Function. NIntegral-command computes the definite integral \int_a^bf(x)\mathrm{d}x numerically.
CAS Syntax
- NIntegral[ <Function>, <Start x-Value>, <End x-Value> ]
- Let a be the Start x-Value, b be the End x-Value and f the Function. NIntegral-command computes the definite integral \int_a^bf(x)\mathrm{d}x numerically.
- Example:
NIntegral[ℯ^(-x^2), 0, 1]
yields 0.746824132812427.
- NIntegral[ <Function>, <Variable>, <Start Value>, <End Value> ]
- Let a be the Start x-Value, b be the End x-Value, f the Function and t the Variable to integrate. NIntegral-command computes the definite integral \int_a^bf(t)\mathrm{d}t numerically.
- Example:
NIntegral[ℯ^(-a^2), a, 0, 1]
yields 0.746824132812427.
