|π-3|+|π-4|咋么算
|π-3|+|π-4|咋么算

|π-3|+|π-4|咋么算
π≈3.14
所以|π-3|+|π-4|
=π-3+4-π
=1

π-3＞0 |π-3|=3-派
派-4＜0 |π-4|=派-4
|π-3|+|π-4|=-1

|π-3|+|π-4|咋么算 数值：sin9π/4+cos2π/3+tan5π/4 数值：sin9π/4+cos2π/3+tan5π/4 若3π/4 已知4/3π 已知3π/4 已知3π/4 已知3π/4 已知3π/4 已知3π/4 3π/4 设3π/4 已知3π/4 知道3π/4 3π/4 已知3π/4 已知3π/4 2π-3π/4等于多少
