Hi, Can some one Please help. centre mas question
The 'question' is in blue on my drawing, I have attempted it but I dont believe it is correct ,I made up my own value for variable c , as they didnt give values
(I dont really understand it)
They are saying that your region is bounded by the parabola and the two vertical lines and where is just some positive constant (the part).
So when you set up your integral to find , we have:
Now, if , then we would have:
You can solve that directly if you want. But what we noted earlier is that both and are even functions, and using the fact I gave you in my last post, we can convert each integral so that we have:
Doesn't really do anything too much but it makes evaluating the definite integral a little easier. We like zeroes .. kind of..
