Calculate a Sum Product

Calculator for sum products, a product Π of sums Σ. The inner sum with the running variable j runs from o to p, the outer product with the running variable i runs from m to n. Only the variables i and j may occur in the sum term. The basic arithmetic operations + - * / are allowed, as well as the power function, like pow(j#i) for ji. Further allowed functions are sin(), cos(), tan(), asin(), acos(), atan() and log() for the natural logarithm. Also, the constants e and pi can be used. If i≠j is chosen, factors with equal running variables are omitted. The double product can quickly lead to very high values.
