Integral Operator
Operator
Description
Keyboard Shortcut
Returns the indefinite integral of f(x).
Ctrl+Shift+I
Returns the definite integral of f(x) from a to b.
Operands
f is any scalar-valued function. When calculating the definite integral f must be defined in the closed interval [a, b]. The function can be complex, except in the case of infinite limit integration. It can be a function of any number of variables.
x is the variable of integration.
a, b are real scalars. They must have units compatible with x.
Additional Information
You can create multiple integrals by inserting the integral operator multiple times.
Sharply peaked integrands, discontinuous integrands, or integrands whose shape is not readily characterized by a single length scale may not evaluate accurately. You can integrate such functions by parts.
This operator may also be evaluated symbolically for integrals with a closed-form solution.
