wait how did you get the second line from the original equation? i got different working out

okay think I got it now. yes I did get (pi - 2) units^2Sorry, I didn't see the function correctly.
(x+2)^2 = 4-x^2
Since I've caused you some confusion, i'll post the solution
x^2 + 4x +4 = 4-x^2
2x^2 +4x = 0
x=0 and -2. Check by subbing it back into each function to make sure they yield the same value. In this case they do.
Now it's
You can calculate the first one quite easily. It's just 1/4 of the area of a circle. The radius is 2, so pi(2)^2 / 4 = pi
Now it's
The integral isn't hard to find, i'll assume you know how to do it.
The answer should be pi-2
lol wut? the answer is (2x + 5)^8 / 16 + CLet
=
ah yes yes, sorry LMAo, I'm all over the shop today. yes find the indefinite integral (primitive function)Did you mean integrate?
I made this question up. ie. it's not from anywhere.Is this a trick question?
60 degrees. (180 / 6) = 30 degrees, its 2 o clock - 30*2I made this question up. ie. it's not from anywhere.
Are you serious? 60 degrees? lol... Think.
What's the answer in exact value??What happened to MrBrightside's marathon thread? Anyway,
New Question:
Find the area of the shaded region.
If we square x, don't we square
lmao. Think.60 degrees. (180 / 6) = 30 degrees, its 2 o clock - 30*2
note: divide by 6 because there are 6 hours within the 180 degrees. i.e 1,2,3,4,5,6
It's 60 degreez.lmao. Think.
60 deg would be 4:00
