How do you find the maclaurin series expansion of #e^(7x)ln((1-x)/3)#?
Note I've left the logs as
Taylor Expansion:
So Maclaurin series will be:
I'm only going to compute up to the second derivative, ie quadratic terms of x because this function will just get so messy it'll be easy to make a simple mistake. If you need more either work them out or use one of the various online tools.
Using product rule and chain rule:

To find the Maclaurin series expansion of , we use the formula for the Maclaurin series expansion of a composite function. The formula states that if and have Maclaurin series expansions, then the Maclaurin series expansion of is obtained by substituting the series expansion of into , term by term.
Here, and .
The Maclaurin series expansion of is .
For , we need to find its Maclaurin series expansion. We'll use the properties of logarithms and the geometric series to expand .
Now, multiply by :
Now, substitute this series expansion into the Maclaurin series expansion of :
This gives us the Maclaurin series expansion of .

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
