I'm wondering why this integral won't be evaluated. http://puu.sh/h2E2t/172302af91.png I have entered everything correctly, it seems. However, it keeps giving me the same integral, unevaluated, as the result. Thanks!
Log and Cos should both start with capital letters.
You misspelled Log and Cos. Capital letters required.
In[1]:= Integrate[Log[2 + Cos[x]], {x, 0, Pi}] Out[1]= \[Pi] Log[1/2 (2 + Sqrt[3])]
