# Python, Beta Decay

### Description

Calling math.tan on the desired ouput gives 0.777…, so it suffices to replace tan with atan and 749 with 7/9.

### Code

import math, decimal
print(decimal.Decimal(math.atan(7/9)))


The output is actually 0.66104316885068692410953872240497730672359466552734375 on my machine, which rounds the (intermediate) result of math.atan(7/9) differently.

• Yep, you got it :D – Beta Decay Aug 15 '15 at 15:53
