Question

求VB高手写出下列数学表达式的vb算术表达式，急急急，在线等！

Answer 1

解：
(1) Sqr(x*x+y*y)
(2) Cos(30*3.1415926/180)^2 - Sin(30*3.1415926/180)^2
(3) 1+(x /(1+(x /(1+x))))
(4) Log(x)/ Log(10)+ Exp(3)/ x ^(2/3)
(5) Sqr(Abs(2*x1 + 3*x2*x3))
(6) Log((Exp(x*y)+Abs(Atn(Z)+Sin(x)^3))/(x + y +z))

Answer 2

X^3 表示 X的3次方

sqr(X)表示x.根

VB好像没有ln,log表示lg, ln(x) = log(x)/log(10)
自然对数底e的3次就是 =exp(3)

Answer 3

1 a = sqr(x ^2+y^2)
或 a = (x ^2 + y ^2) ^ 0.5

2 a = (cos(30/180*3.14) ) ^2 - (sin(30 /180*3.14))^2

3 a = 1 + x/(1+(x/(1+x)))

4 a = log(x) + exp(3)/((x^2)^(1/3))

5 a = sqr(abs(2*x1+3*x2*x3))

6 a = log((exp(x*y)+abs(((tan(z)) ^ (-1)+(sin(x))^3))/(x + y +z ))
