sum from n=0 to infinity of cos(pi/2)

n = 0 \sum \infty cos (\frac{π}{2})

0

Solution steps

n = 0 \sum \infty cos (\frac{π}{2})

\sum 0 = 0

= 0

f (x) = 4 x^{2} - 5 x, (- 1, 9)

n = 1 \sum \infty \frac{3 ^{n}}{n ^{3}}

\int_{0}^{1} 7 x x^{2} + 9 d x

\int \frac{x ^{2} + 1}{( x - 7 ) ( x - 6 )} d x

n = 1 \sum \infty x^{2 n}
