find y0(x),y1(x),y2(x),y3(x) in Picard's iteration scheme used to solve (dy/dx)=2*x*y, y(0)=1
Compare the result with the exact solution.

Bleedin hell!..Beam me up Picard!?..I failed iteration..so they made me repeat it..(joke!) ..Anyways (looking up all the Banana interval stuff and the fundy theory of calc and lots of lemon thingys)..

y1(x)=yo+INT(2*x*yo)

>y1(x)=yo+x^2=1+x^2 given IVC

>y2(x)=yo+INT(x*y1)= yo+INT(2*x+2*x^3)

>y2(x)=yo+x^2+x^4/2

>y3(x)=yo+INT(2*x*y2(x))

>y3(x)=1+x^2+x^4/2+x^6/6

If you integr8 like dy/y=2x*dx

You get x^2=lny and y=e^(x^2)

Now if e^x=1+x+x^2/2!+x^3/3!+ etc

Then e^(x^2)=1+x^2+x^4/2!+x^6/3!+..etc which is just the first three terms of ur approx!

The math guy is out at mo..an this mother ran 2.6min on the heuristic alogorthm parser thingy!

instead of asking other people to do your work for you, why not get tutoring so you can do it yourself? thats the only way youll survive in life
