Calculator: trig functions use degrees, not radians

According to the [KB article about the search bar calculator](

https://help.niagaralauncher.app/article/173-integrated-calculator), the functions sin, cos, and tan take an argument in radians. The actual behavior is of an argument in degrees: cos(3.14) gives 0.998 and cos(180) gives -1.

I am using version 1.15.11.
