In Taylor Series at http://tutorial.math.lamar.edu/Classes/CalcII/TaylorSeries.aspx in example 3 why not the author has taken the derivative of x^4 and just too the derivative of exponential?

Answer 1

He was saying that the power series of
\[x^4 e^{-3x^2} \]
is just
\[x^4 \cdot \left( \text{ The power series of }e^{-3x^2} \right) \]
to save time.

Answer 2

Taylor Series *
