In Calc do

'sin(45 deg)
u s

Result: 0.0137073546047
Expected result: 0.707106781187

The actual result equals to sin(pi/4) in deg mode whereas the expected
result of "the sine of 45 degrees" is the one documented in
(info "(calc) Trigonometric and Hyperbolic Functions").

The same applies for other trigonometric functions and for other values
of 45 or the 'deg' unit (i.e. 'rad or 'grad').
