Riemann Sums

You can work with partitions.

> gRiemann(x^2+3,x=[-1,-0.5,0.5,1.5,2],[-0.75,0.0,1.1,1.5]);

You can select from standard methods.

> gTrap(x^2+3,x=-1..3,4);

You can even work with "n" rectangles.

> Ln:=Lsum(x^2+3,x=-1..3,n);

Find the limit of the last result.

> limit(Ln,n=infinity);

Find definite or indefinite integrals.

> int(x^2+3,x=-1..3);

Estimate definite integrals given data.

> xd:=[1,2,3,4,5,6];

> yd:=[2.2,3.4,2.7,1.5,2.7,3.2];

> gdiscreteLsum(xd,yd);

Visualize Riemann sums for functions of two variables.

> gMsum3d(x^2+y^2,x=-2..2,y=-2..2,4,4);
