(2x^9y^n)(4x^2y^{10})=8x^{11}y^{20}\\\\(2\cdot4)(x^9\cdot x^2)(y^n\cdot y^{10})=8x^{11}y^{20}\\\\8x^{9+2}y^{n+10}=8x^{11}y^{20}\\\\8x^{11}y^{n+10}=8x^{11}y^{20}\Rightarrow n+10=20\ \ \ |-10\\\\\boxed{n=10}

\text{Used:}\\a^n\cdot a^m=a^{n+m}

Find a power series representation of e^x sin(x)
liberstina [14]
The Taylor series is defined by:
f(x) = \sum \frac{f^n (a)}{n!} (x-a)^n

Let a = 0.
Then its just a matter of finding derivatives and determining how many terms is needed for the series.

Derivatives can be found using product rule:
f^n (x) = e^x g^{n-1} (x) + e^x g^n (x)  \\ g^0 (x) = sin x

Do this successively to n = 6.
f^1 (x) = e^x (sinx +cos x) \\ f^2 (x) = e^x (2cos x)  \\ f^3 (x) = e^x(2cos x - 2sin x)  \\ f^4 (x) = e^x (-4 sin x)  \\ f^5 (x) = e^x(-4sinx -4cos x) \\ f^6(x) = e^x(-8cos x)

Plug in x=0 and sub into taylor series:
e^x  sin x = x+x^2 +\frac{x^3}{3} -\frac{x^5}{30}-\frac{x^6}{90}...

If more terms are needed simply continue the recursive derivative formula and add to taylor series.
