# How to evaluate derivative in a sequence cmd to create a list for taylor series

Hello,

I am trying to generate a taylor series for a function using the code

L_1=Sequence(Derivative(f, x, k) / k! (x - x_o)^k, k, 0, n, 1)

So, L_1 would generate a list of each piece of the summation of the taylor series up to a value of n specified by the user.

My issue here is that I can't seem to evaluate the derivative at x_o. Is there any cmd in geogebra that allows you to evaluate functions

So for instance if you typed in f'(3) this would evaluate the derivative at 3.

However, if you type Derivative(f, x, k)(3) this multiplies the kth derivative by 3 instead of evaluating it at 3.

I am looking for something like Evaluate(f(x), 3). If this existed then it would solve the issue. I tried guessing some cmds but nothing comes up usable.

I'm sure there should be a simple answer to this. Thank you for your help!

Have you tried this? https://wiki.geogebra.org/e...

That's a good question. I also couldn't find a simply way to do that (though I am not that familiar yet with the intricacies of GeoGebra). As a workaround you can use LeftSum:

Btw, GeoGebra already has a TaylorPolynomial command.
