$\int\limits_{?}^{?}e ^{cosx}$

3. Goten77 Group Title

i only use wolfram wen i have no idea wut to do

4. darthjavier Group Title

Lol. I can't see very well the function

5. hartnn Group Title

put cos x = u

6. Goten77 Group Title

i just didnt take them off

7. Goten77 Group Title

but ye this integral is impossible right? unless u do something imaginary or unnecessary

8. hartnn Group Title

yeah, it doesn't have closed form.... not in any standard mathematical function....

9. darthjavier Group Title

the function is $e^{\cos x}$, isn't it? I guess you can do it with series. Remember, if a function is continuous (like this), THEN is integrable.

10. Goten77 Group Title

yes thats the function
