- NIntegral( <Function>, <Start x-Value>, <End x-Value> )
- Computes (numerically) the definite integral \int_a^bf(x)\mathrm{d}x of the given function f, from a (Start x-Value) to b (End x-Value).
- Example:
NIntegral(ℯ^(-x^2), 0, 1)
yields 0.75.
Hint: In the CAS View the following syntax can also be used:
- NIntegral( <Function>, <Variable>, <Start Value>, <End Value> )
- Computes (numerically) the definite integral \int_a^bf(t)\mathrm{d}x of the given function f, from a (Start value) to b (End value), with respect to the given variable.
- Example:
NIntegral(ℯ^(-a^2), a, 0, 1)
yields 0.75.
