Problem 473. old wine in a new bottle?
- You have been given an apparently brand new unary function XXX,
- that maps some ordinary scalars to scalars,
- please guess if this XXX is 'new wine' or 'old wine',
- that is functionally equivalent to an already built-in function,
- such as sin cos sqrt log10 etc.,
- for positive inputs between 0.2 to 0.8.

test case 2 is incorrect. the given function will only return positive values, which means it is not equivalent to sin (and therefore new wine)

adding 'for positive inputs between 0.2 to 0.8'
