I want someone to explain this to me in depth, I really could just look up the answers, but I really dont learn that much from doing that, so hopefully someone on /sci/ can help me with this

>>	Anonymous Mon Mar 28 14:29:36 2011 No.2789056 I want to know the answer to this, also could someone annotate the answers a) b) c), I want to know what methods to use for each because Im shit

You're function g'(x) is definied piecewise. Obviously, I mean when you look at the graph you know what function g'(x) is.
I called it Dg, the derivative of g.
Now that you know the funtion you can integrate it piece by piece. g(x)=int(g'(x))+c
you find out what c is if you consider g(0)=5 (it says so in your pic.)
I.e. g(0)=int(g'(0))+c

>>	Anonymous Mon Mar 28 14:35:36 2011 No.2789077 >>2789064 OP here So you mean its this? 5∫(g'(x))+C Where you would integrate from 0 to 3?

It's some function which starts at x=0, y=5.
you know that when you then take 2 steps to the right, you add to g(x) (the integral of g'(x)) the value of A=(r^2·pi)/4=pi, because that's the value under the curve of g'(x) from 0 to 2.
Then from 2 to 3 you know that g' is linear, so the value of g(x) goes up quadratically (because the integral of a linear function is a quadratic function) and you <see> that the value will rise +1,5 since that's the area under the curve. and so on.
you can reconstruct g(x).
And I have drawn you a pic (youout the condition g(0)=5, you you have to shift the function up in your mind.)
kthxbye.

>>2789290
that's a silly question.
why would I not post pics of some cutie pies?
I posted two mathematica screenshots, so stop complaining :P
(also, I always post emma here when talking to an OP, so I don't have to take a tripcode. Except for I switched back to the one where I don't have mathematica running but also no more emma pics, so it's her)
