Plot calculation functions
This topic provides you with a list of the mathematical functions that can be used when creating a new user-defined plot, and a description about the action that the function performs on the existing plot.
| Function | Description |
|---|---|
| Sin | Calculates the sine of the expression (in radians). |
| Cos | Calculates the cosine of the expression (in radians). |
| Tan | Calculates the tangent of the expression (in radians). |
| Log | Calculates the logarithm of the expression (base e). |
| Log10 | Calculates the logarithm of the expression (base 10). |
| Exp | Exponentiate the expression (base e). |
| Abs | Calculates the absolute value of the expression. |
| Sqrt | Calculates the square root of the expression. |
| Sign | Evaluates to 0, 1 or -1 if the expression evaluates to 0, >0 or <0 respectively. |
| Nint | Calculates the nearest integer to the expression. |
| Constant | Uses a constant value for the expression. |
To convert from degrees to radians, multiply by pi/180 (about 0.01745) before applying Sin, Cos or Tan.
