sum from n=1 to infinity of 4/(pi^n)

n = 1 \sum \infty \frac{4}{π ^{n}}

converges

Solution steps

n = 1 \sum \infty \frac{4}{π ^{n}}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 4 \cdot n = 1 \sum \infty \frac{1}{π ^{n}}

Apply Series Ratio Test:

converges

= 4 converges

= converges

\int x^{2} 6 x + 3 d x

f (x) = \frac{1}{5 x + 7}

\frac{1}{( 1 + x )}

y^{^{''}} + 5 y^{^{'}} + 6 = 0

y = sin (sin (x)), (4 π, 0)
