Answer:

  see below for the tables

Step-by-step explanation:

The differential equation is separable, so the solution is ...

  \displaystyle\dfrac{dy}{dx}=2xy\\\\\int{\dfrac{dy}{y}}=\int{2x}\,dx\\\\\ln{y}=x^2+C\\\\\text{Considering the initial condition, $C=-1$}\\\\\boxed{y=e^{x^2-1}}

__

The values for yn are y+y'·h = y+2xyh. We take the "absolute error" to be the (signed) difference between the calculated yn and the actual value y(x).

It's answer will be 36x10^5 As we have (4x10^10)(9x10^-5) All terms of this expression are being multiplied So we will solve it in two parts, simple terms and terms having powers (4x9)(10^10x10^-5) As we know when same terms having some powers are multiplied, their powers are added (36)(10^(10-5)) (36)(10^5) So it will become 36x10^5
