Chứng minh : \(\frac{1}{1}-\frac{1}{1}+\frac{1}{2}-\frac{1}{3}+\frac{1}{5}-\frac{1}{8}+\frac{1}{13}-\frac{1}{21}+\frac{1}{34}-\frac{1}{55}+...< \frac{3}{10}\).
Lấy \(\varphi=1,618\); tính \(\frac{\varphi}{1\cdot2}+\frac{\varphi}{2\cdot3}+\frac{\varphi}{3\cdot5}+\frac{\varphi}{5\cdot8}+\frac{\varphi}{8\cdot13}+\frac{\varphi}{13\cdot21}+\frac{\varphi}{21\cdot34}+\frac{\varphi}{34\cdot55}+\frac{\varphi}{55\cdot89}+\frac{\varphi}{89\cdot144}+...\)
\(A=\frac{55}{11X16}+\frac{55}{16X21}+\frac{55}{21X26}+\frac{55}{26X31}+\frac{55}{31X36}+\frac{55}{36X41}\)
Tính \(A=\frac{55}{11X16}+\frac{55}{16X21}+\frac{55}{21X26}+\frac{55}{26X31}+\frac{55}{31X36}+\frac{55}{36X41}\)
Tính biểu thức A bằng cách nhanh nhất
