Topic: About the sum() function
I basically want to plot this function:
But how do I enter this using the sum() function? The variable of the summation is x, does this mean I cannot use the x meaning the variable on the x-axis anymore?
How to plot this? Thanks.
Re: About the sum() function
In Graph 4.3 this is not possible because x is used for the summation as you have noticed.
However in the beta version of Graph 4.4 this has been fixed so you can write it as:
f(x)=sum(sin(x*2^n)/2^n, n, 1, 10)

Re: About the sum() function
Wonderful, thanks!
However, since I updated to the last beta version, scrolling makes the plotting range zoom out to extraordinary values like -4E10 to 4E10. Is this correct?
Re: About the sum() function
No, that is not correct.
That is a bug.
I have fixed it now in build 492 of the beta version.
