这次的亚洲梦想杯是中国队赢了还是韩国队?

实验30

•(2) 编写计算关于 x和y变量的函数式子 的程序(其中x=5,y=9)。–(x ^ 3 + x * y + y ^ 3) / (2 * x * y)•(3) 编写计算y=ln20+|x-16|的程序。–Math.Log(20) + Math.Abs(x - 16)•(4) 编写计算y=0.231x+1.36值的程序。–0.231 * x + 1.36

•(5)一个物体做斜抛运动,设初速度为v0,斜抛方向与地面夹角为θ,落地时所用的时间 ,落地时物体运动的射程 (其中重力加速度g=9.81米/秒2,θ的单位为:弧度)。编写程序,计算它落地所需时间和落地时运动的射程。要求:①用InputBox函数输入初速度为v0和角度θ(单位为:度);②在程序中,重力加速度g定义为符号常量。– t = 2 * x * Math.Sin(y * Math.PI / 180) / g–s = x * Math.Sin(2 * y * Math.PI / 180) / g

•(4) 用IF…THEN…ELSEIF…ENDIF语句编写根据成绩,给出等级的程序。等级划分如下:•90分以上 A •80-89分 B•70-79分 C•60-69分 D60分以下 F
