为什么我的labview里没有三角函数模块呀？

8.0在express模板里……

What trigonometric function do you want particularly? The sin, cos, tan, cotan, sec, csc, corresponding inverse functions, hyperbolic functions, and even sinc function are all available in the basic version of LV.
In LV 8, they are in Mathematics palette, and Numeric palette in earlier versions.
