Hai everyone
a
Im new in this forum so i would like to post(hopefull not stupid) quieston. Is there a possibility of tiping in the "Pi" as a function, as we do so with Sigma ? i mean if there is a sigma u can type it in the Calculator as E(C=1,5,X^2)
is there a way to do so with multiplications using the TT (Pi) symbol ?

If you don't find it, you can use logarithms and exponentials to do the same:

PROD x_k=e^{SUM ln x_k}
