在matlab程序中sin(2)中的2表示
A: 2度
B: 2弧度
A: 2度
B: 2弧度
举一反三
- 在MATLAB中,A = [0:1/2:2]*pi,那么sin(A) =
- 弧度=_______度;2弧度=________度;=________弧度;________弧度.
- 函数[img=79x27]180355ae2690a03.png[/img]在x=2处的二阶泰勒展开式为 A: exp(sin(2))+cos(2)*exp(sin(2))*(x-2)+exp(sin(2))*(sin(2)/2-cos(2)^2/2)*(x-2)^2 B: exp(sin(2))+cos(2)*exp(sin(2))*(x-2)-exp(sin(2))*(sin(2)/2-cos(2)^2/2)*(x-2)^2 C: exp(sin(2))+cos(2)*exp(sin(2))*(x-2)-exp(sin(2))*(sin(2)/2+cos(2)^2/2)*(x-2)^2 D: exp(sin(2))+cos(2)*exp(sin(2))*(x-2)+exp(sin(2))*(sin(2)/2+cos(2)^2/2)*(x-2)^2
- 在MATLAB中,命令“zero(2)”表示()
- 多项式2x3+5x4-2x+6x2-8在MATLAB中表示,正确的是________。 A: [5, 2, 6, -2, -8] B: [5, 6, 2, -2, -8] C: [2, 5, -2, 6, -8] D: [-8, -2, 6, 2, 5]
