From IEEE-754-2019, it is known that the domain of trigonometric functions is the set of real numbers.
Example 1. Calculate
sin(20100)
\sin(20^{100})
sin(20100)
and
cos(20100)
\cos(20^{100})
cos(20100)
in MATLAB.
Let’s just post the picture directly.
However, the correct values are 0.4559851… and -0.8899874…, respectively (as provided by ISRealsoft).
Thus, the outputs of MATLAB are all incorrect results.
