I have a Question in regards to a Power series questions that I have almost completed.
My Question looks like this:
The function f(x)= 5xarctan(4x) Find:
C1: Which I found to be 0
C2: Which I found to be 0
C3: Which I found to be 20
C4: WHICH I CANT FIGURE OUT, I thought it was 20x^4/3 But it is not right.
As well Find R: Which I cant figure out...
If anyone could help that would be great!
