Q: Units
Hi,
I did some experiment with constants and units in CAS-Mode but did not understand the result. Could somebody please explain: entered 1/SQRT(E_0*µ_0) without units and got 299792458, which seems to be the speed of light -> correct. (Of course SQRT ist the squareroot-key and everything is printed nicely on screen) Tried the same _with_ the built-in constants and units: 1 --------------------------------- SQRT(8.85..._F/m *1,2..._H/m) leads to 8.98E16_m²/(F*H) It seems to me, the square-root did not get evaluated... Adding MKSA() into the root gives 8.98...E16_m²/s² sqrt(8.98...E16_m²/s²) again leads to the result I expected in first place. The speed of light with correct units... can somebody please tell me what I'm doing wrong? |
