The following table shows non-intrinsic math functions that can be derived from the intrinsic math functions of the System.Math object. You can access the intrinsic math functions by adding Imports System.Math to your file or project.
| Function | Derived equivalents |
|---|---|
| Secant (Sec(x)) | 1 / Cos(x) |
| Cosecant (Csc(x)) | 1 / Sin(x) |
| Cotangent (Ctan(x)) | 1 / Tan(x) |
| Inverse sine (Asin(x)) | Atan(x / Sqrt(-x * x + 1)) |
| Inverse cosine (Acos(x)) | Atan(-x / Sqrt(-x * x + 1)) + 2 * Atan(1) |
| Inverse secant (Asec(x)) | 2 * Atan(1) – Atan(Sign(x) / Sqrt(x * x – 1)) |
| Inverse cosecant (Acsc(x)) | Atan(Sign(x) / Sqrt(x * x – 1)) |
