Calculation of Finite Sums

You can calculate the sum of values of an expression F, depending on variable i , using function

sum(F,i,m,n)

 

m and n stand for minimal and  maximal values of i. While calculating of the sum, variable of summation changes from m to n with increment 1.

 

When sum is being calculated variable of summation should not be defined.

 

Example

sum(n^2,n,1,10)           ; result: 385.
