How to integrate or differentiate given a equation like for example

y = ∫(x^3 + 4sinx)dx, lower limit 10; upper limit = 50.

Thank you for the efforts towards explaining me integration. Thank you very much

But my doubts was not this. I wanted to integrate using the labtalk scripts or using codes in the scripting window. I will be helpful if you can provide me the codes for the same.

This should work.


dataset ds1 = data(10,50,0.1);
dataset ds2 = ds1^3 + 4*sin(ds1);
int nn = ds1.GetSize();
double dd = integrateXY(ds1, ds2)[nn];
dd=;

In my origin the integrate function is integ1 and the syntax is different. May be because of this reason it did not work.

In origin there is not function to directly integrate a function like in a calculator.
