Available functions: (always use lower case variables)

Misc. Math | * is multiply; / is divide; ^ is power; abs(x); unit step function Ua(x) = (1+sign(x-a))/2 |

Log and exponential | exp(x); natural log = log(x); base 10 log = log(x)/2.303 |

Root (x>=0 only) | sqrt(x) or x^0.5; cube root = x^(1/3)... |

Trig | cos(x); sin(x); tan(x);atan(x); acot(x); acos(x); asin(x) |

Hyperbolic Trig | sinh(x); cosh(x); coth(x); asinh(x); acosh(x); atanh(x); acoth(x) |
