Calculus in processing ... please wait
product function calculates online the product of the terms of the sequence whose index is between the lower and the upper bound.
product(n;1;4;n^2), returns 576, ie 1^2*2^2*3^2*4^2

### Calculate product elements of sequence

product function calculates online the product of the terms of the sequence whose index is between the lower and the upper bound.

The calculator is able to calculate online the product of the terms of a sequence between two indices of this sequence.

## Product calculation of terms of a sequence

The calculator is able to calculate the product elements of a sequence between two indices of this sequence.

To get the product elements of a sequence defined by u_n=n^2 betwwen 1 and 4 , enter : product(n;1;4;n^2) after calculation, result 576 is given, prod_(n=1)^4 n^2=1^2*2^2*3^2*4^2=576.

## Product calculation of elements of an arithmetic sequence

The calculator is able to calculate the product of elements of an arithmetic sequence between two indices of this sequence.

To get the product elements of an arithmetic sequence defined by u_n=3+5*n between 1 and 4 , enter : product(n;1;4;3+5*n) after calculation, the result is given.

## Product calculation of elements of a geometric sequence

The calculator is able to calculate the product of elements of an geometric sequence between two indices of this sequence.

To get the product elements of an geometric sequence defined by u_n=3*2^n between 1 and 4 , enter : product(n;1;4;3*2^n) after calculation, the result is given .

#### Syntax :
