## query...

@Adri van der Meer why ''i to 10 " not "i from 1 to 10" or some different number.

## Write the program...

@Carl Love I am getting that sum by manual addition. Can you please rewrite my program correctly to get that sum. Also can we give a restriction to the number of roots satisfying the condition that component sum is a constant.

When I plot the function in Maple I didn't get the actual curve.

i.e at point t=0 I am not getting the value f(0) rather I got the value being evaluated from the function f(t) putting t=0

In my case f(0) is not equal to f(t) at t=0.
