I think it was about 7 years ago, I was thinking about why Z^2=X^2+ Y^2, my brain just come out the diagram I have attracted very quickly.
So, 2xy+Z^2 = (x+y)^2
Z^2=x^2+Y^2
Hey I think it should have more solution and reason!
I can't upload the image, can somebody tell me? my file size is 628 kb is it the reason?

Hey guys, I have forgot how to do integration can you do the following calculation for me?
parabola formula: y=0.048x2 + 0.24x
length between x=0 and x=-5
please show me the step clearly as I have forgot how to do integration, thanks!
