4 输入sqrt(4-x^2),按确定;5 新建好了一个函数y=sqrt(4-x^2);6 点击绘图,选择绘制新函数;7 我们就创建好了函数y=sqrt(4-x^2)及其图像。
在数学和编程中,sqrt函数通常指的是平方根函数。拓展知识:这是一个用于计算一个数字的平方根的函数。在数学上,平方根是一个数x,使得x×x等于y(其中y是我们正在寻求的值)。例如,如果我们要计算数字4的平方根,那么平方根的结果就是2,因为2×2=4。在编程中,sqrt函数通常会作为库...
在MATLAB中log表示ln的意思。4 第四,在上述代码末尾添加set(gca,'FontSize',15,'Color',[0 0 0]),改变坐标字体大小和框图颜色。5 第五,保存和运行上述改进后的代码,得到的函数图像更加美观。6 第六,可以改变函数的定义域,让值域更宽广,比如使x=-15:0.1:15,再次运行代码脚本...
double sqrt(double x) 返回 x 的平方根。sqrt的返回值是double。根据实际情况定义,如定义变量int x = sqrt(4),此时接收的返回值的变量x为整型,结果为2。如定义变量double x = sqrt(4),此时接收返回值的变量x为double类型,结果为2.000000。
4. 倒数的近似值计算 4.1 第一次求近似值 对y = \frac{1}{x} 等式两边取log函数,得到: log(y)=-log(x) 然后将x和y都用各自的E和M替换,得到: log(y)=log((1+m_y)*2^{e_y})=log(1+m_y) + e_y log(x)=log((1+m_x)*2^{e_x})=log(1+m_x) + e_x 因此得到 log(1...
