- saagarjha 5y agoΣ(1/n^2,n,1,∞) is a calculation. That TI-89 evaluates it to π^2/6 makes it good at doing them.
- dan-robertson 5y ago1. That’s not a calculation. It’s a special case you either need to know or have to be clever to compute. A calculation might be, say, compute zeta(2). But I don’t really want to argue about semantics. 2. This can evaluate this correctly on the (slightly later) HP-49G+ So given this new information, will you change your mind or try to find some other silly example?
- armanboyaci 5y agoMaybe did you mean it is not arithmetic?
- dan-robertson 5y agoTranscendental functions are not arithmetic, but they are also not algebra (in the CAS sense of the word)
- armanboyaci 5y agoAccording to wikipedia: "arithmetic also includes more advanced operations, such as [...] exponentiation, logarithmic functions, and even trigonometric functions, in the same vein as logarithms (prosthaphaeresis)."
