Origin Ver. and Service Release (Select Help-->About Origin): 8.0
Operating System: Windows XP
Does anyone know how to plot this two functions:
- modulus functions, e.g. |sin(x)|
- Series of n functions, e.g. Sum(x^n) with n= 1,2,3,….,n-1,n
Thank you very much in advance

You could easily get what you want by using the Set Values dialog. Suppose you have put the X values in column A, and want to get the values of column B by using functions you given.
1. Use the |sin(x)| function
Please highlight column B, right click on it to select Set Column Values from the context menu. Then input abs(sin(col(a))) into the box as the following screenshot shows and click OK button to get the values.
2. Use the Sum(x^n) function ,and suppose n = 3.
Please highlight column B, right click on it to select Set Column Values from the context menu. Then input ds into the upper edit box and input the following scripts into the Before Formula Scripts panel
int n = 3;
range ra = !col(a);
dataset ds;
ds.setsize(ra.getsize());
ds=0;
for(int ii=1;ii<=n;ii++)
{
ds += ra^ii;
}
as the following screenshot shows and click OK button to get the values.
