Question

解方程！~~~~~~~~~

sin{sin[sin(sinx)]}=cos{cos[cos(cosx)]}
（作出加50分！！说到做到！~~~~~`）急！

Answer 1

哇....有意思，下去做着试试....
-----------------------------
补充：

两天都没有解出来，考察是不是有实数解：

A1 = cosx ................(1.000,0.000)
B1 = sinx ................(0.000,1.000)

A2 = cosA1 ...............(0.540,1.000)
B2 = sinB1 ...............(0.000,0.841)

A3 = cosA2 ...............(0.858,0.540)
B3 = sinB2 ...............(0.000,0.746)

A4 = cosA3 ...............(0.654,0.858)
B4 = sinB3 ...............(0.000,0.678)

0.678 > 0.654、0.858 > 0.000

交叉，有实数解....唉...遗憾，没有解出超越方程，呵呵
