The Maclaurin expansion of e^(2x) is 1 + 2x + 2x².

I think the answer should include the constant term and the linear term, but I’m not confident about the second-order term. I hope I remember the right formula!

I remember practicing a similar question where we had to find the expansion for sin(x). I think the second-order term is crucial here, but I can't recall the exact coefficients for e^(2x).

I think the Maclaurin series for e^x is just the sum of the derivatives at zero, but I'm not sure how to apply it to e^(2x).

I feel like I might be mixing up the coefficients for the terms. Is it just 1 and 2 for the first two terms, or do we need to consider something else?
