NIntegral[ <Function f>, <Start x-Value a>, <End x-Value b> ]
Computes the definite integral \int_a^bf(x)\mathrm{d}x numerically.
範例:
NIntegral[ℯ^(-x^2), 0, 1] yields 0.746824132812427.
NIntegral[ <Function f>, <Variable t>, <Start variable-Value a>, <End variable-Value b> ]
Computes the definite integral \int_a^bf(t)\mathrm{d}t numerically.
範例:
NIntegral[ℯ^(-a^2), a, 0, 1] yields 0.746824132812427.
