Pico is equipped with a standard set of native transcendental functions, that is the functions readily available on most pocket calculators. A first sequence consists of the three basic trigonometric functions and their inverse:
Note that arguments of sin, cos and tan as well as values returned by arcsin, arccos and arctan are expressed in ¹-radials. Moreover, the arguments of arcsin and arccos are restricted to the interval [-1, 1].
The next sequence consists of the sqrt, exp and log functions:
The argument of the
sqrt
function cannot be negative; the argument of the
log
function is required to be strictly positive.
