:∫(expression, variable)

Finds an integral of an expression as related to a variable.

:∫(expression, variable, valueOfC)

Finds the integral of the expression as related to a variable, then adds valueOfC to it.

:∫(expression, variable, lowerRange, upperRange)

finds the value of an integral between two values.


  • 2ND + 7


:Disp ∫(f(x),x)
:Disp ∫(f(x),x,0,1)

This will display x^3/3+2^x+x and 7/3. x^3/3+2^x+x is the integral of x^2+2x+1, and 7/3 is the integral's value between 0 and 1.
