Hi,

I have a cfx-9850gc plus, it has served me well for as long as I've had it,
but recently I've had the need to solve primitives/integrals on it
and couldn't find a way to do this.

It solves the expressions given to a numerical value, but what I need is the primitive expression itself.

For example, inserting Primitive(x) and obtaining the expression 1/2(x^2).

I've searched the manual, searched online, couldn't find anything on this.
It can do it, otherwise it wouldn't be able to completely solve the problem once x is supplied (thus showing the numerical value output).

Could someone help please...?

For the time being, I've been using this online integrator:

Thanks in advance!

It can do numeric integration, but not symbolic integration. For symbolic integration, you need a calculator with a CAS, such as the ClassPad.
Integrating an expression numerically directly, rather than first using a CAS and then evaluating the result - is much easier software-wise, and is essentially done the way you'd do it graphically.
