emulate xcas simplify integrate on hp prime g2
Is there a way on the prime to duplicate:

xcas: simplify(integrate(x^2,x,0,x)=1000)

to get the result:

(a^3)/3 = 1000

I can do translate the following xcas expression

fsolve(integrate(x^2,x,0,x)=1000)

to get

14.4224957031

which is an approximation for

10 * 3^(1/3)

---

Thanks.

Hi, in CAS mode:

solve(integrate(x^2,x,0,t)=1000,t)

See last line in the screenshot

Thanks for your reply.

I'm getting 14.4224957031 inside the curly braces.

Perhaps my CAS settings are different.

Did you get the 't' from the [alpha divide T] or from the [x t theta n button] ?

Thanks.

I changed the CAS settings CHK the Exact setting and got the same answer you did.

Thank you very much.

the 't' came from the alpha divide t

Previous image was a screen capture from the PC application. Now I'm attaching photos from the physical calculator with the solve command and with my CAS settings. Hope it helps.

Regards,
