integral of 1/sqrt(9-x^2)
from 0 to 3
The Attempt at a Solution
I integrate it correct to arcsin(x/3) from 0 to 3
Get the correct anwser of pi/2.
But there is another question, At which value of x in the integration region [0,3] does special care need to be taken with the integration? I understand at some point it goes from negatie to positive, but i tried 0,3,pi/2,pi.. none worked.. anyhelp?
