\PiThe Greek letter Pi (\Pi) is used in mathematics to denote the product of a sequence of terms. It is analogous to the summation symbol (\Sigma), but instead of summing, it multiplies the terms. The capital Pi notation is often used in contexts involving products over a set or sequence, such as in probability, algebra, and calculus.
Product of a sequence of terms from a_1 to a_n.
\Pi_{i=1}^{n} a_iProduct of terms in a sequence, often used in financial mathematics to calculate compound interest.
\Pi_{k=1}^{m} (1 + r_k)Product of variables x_1 to x_p, used in algebraic expressions.
\Pi_{j=1}^{p} x_j
