Are trig calculations really easier in radians?
Consider the Euler identity:
iπ
e + 1 = 0
That only takes that simple form in radians.
Do you know the Taylor series for e^x? You can use that, and the above
formula, to derive Taylor series for sin and cos.
Also, you have useful properties like
sin x ≃ x as x → 0
Again, this only works in radians.
