We are given two parts.
00:02
And in each part we have a different function here.
00:06
For the part, we are given the fx equal to 5 out of 3 minus x.
00:12
And then we need to write the power series of this function here, center about x equal to 0.
00:19
In that to do that, we can write the fx here equal to.
00:24
Here we will divide everything by 3, and then we get 5 out of 3, then 1 minus 3.
00:30
X out of 3 and this one it will recall that for the 1 over 1 minus x which will get equal to the summation of the x power n and then goes from zero to infinity and it will replace the x by the 1 by x out of 3 and now we should get equal to the x out of 3 power n goes from zer to infinity and the last time i will multiply everything by the 5 over 3 we equal you we will multiply 5 about 5 over 3 here so x over 3 about n goes from z infinity so this one exactly the function f x here and for the interval of the convergence remember that for this one it will be true for the absolute x will be smaller than 1.
01:38
So because we replace the x by the x out of 3, so this doesn't imply that x out of 3 must be smaller than 1.
01:46
And this one still the same x out of 3 will be smaller than 1.
01:50
And it means then the absolute x will be smaller than 3...
