can someone explain to me why my teacher divided the area into two?
I=[tex]\int[/tex]1,0[tex]\int[/tex](2x-x^2)^.5,0 1/(x^2+y^2)^.5dydx
ugggggh i tried to use the latex...
anyway...
he used the polar coordinate to do this. once he turned it into polar coordinate, he divided the area into 2 bounded by (pi/4 - o d[tex]\theta[/tex]) (1/cos[tex]\theta[/tex] - 0 for dr) and then + (d[tex]\theta[/tex] bounded by pi/2 - pi/4) (2cos bounded by 2 - 0)sorry i don't know how to make this more clear...ask me if you need to clarify
