sum from n=1 to infinity of (-2/3)^{n-1}

n = 1 \sum \infty (- \frac{2}{3})^{n - 1}

converges

Solution steps

n = 1 \sum \infty (- \frac{2}{3})^{n - 1}

Apply Series Ratio Test:

converges

= converges

\int_{3}^{9} \frac{1}{x ^{2} - 1} d x

\frac{\partial}{\partial x} (4 - x^{2} - y^{2})

\int \frac{3 - cos ( x )}{sin ^{2} ( x )} d x

\int_{- 8}^{0} \frac{1}{( x - 8 ) ^{2}} d x

\frac{d y}{d x} = \frac{( y ^{2} + 4 )}{2 x y}
