三角函数的有关计算(1)求出α值 sinα=0.2514cosα=0.6538tanα=2.9516cosα=0.123cosα=0.234cosα=0.345(2)已知sinα=0.2829 ,则tanα=_______(2)已知sinα=0.2829 ,则tanα=_______ 这个请告诉我怎么求 还请问下怎么用计
excel在一个区域中怎样求满足“数字”的求和,例如,一个表格中有0.123,0.234,A.B怎么求数字的和 求公式
1.345*0.345*2.69-1.345*1.345*1.345-1.345*0.345*0.345
1.345 × 0.345× 2.69 -1.345×1.345-1.345×0.345×0.345
2.34x9.9+0.234
计算;1.345^2-0.345x2.69+0.345
0.345²-0.345×2.68+1.345²
0.345²+1.345²-0.345×2.69
2.616+(10.4-0.234/0.65)*0.35
2.34乘9.9+0.234=
