Triple Integral Help

[marcusnicolas1]

I posted this subject somewhere but can no longer find it. I am trying to do a triple integral and I keep coming up with an error message. ... in CAS. When I do it in non CAS mode, it comes up with the exact numerical value with decimal points. I am trying to have it come up with the exact number which is supposed to be 96pi. Can anyone help me with how to put in a triple integral with its limits. Thank you

Hi Marcus,

How do I post the integral

[marcusnicolas1]

I use the actual symbol but here is basically what I do ..... int(int(int(r,z,0,r^2 -4)1,r,2,3)1,x,0,2pi) .... this is supposed to produce (25pi)/2. It does not work. I get error messages. I am thinking it is the way I put it together but I can not figure it out. I had another problem to use but I can not remember what it is.

Have you tried using the integral template on the [c] key? Start from the outer integrand and work inwards.
