Question

Apply the successive approximation formula to compute yn(x) for n ≤ 4. Then write the exponential series for which these approximations are partial sums                                                                                                  

 

                    dy/dx = 4x(y+2x2) ,  y(0) = 0

Expert Solution
Step 1

Given- The IVP is-

dydx=4xy+2x2,   y(0)=0

 

Method Used- 

Picard's method of successive approximation:

yk+1=y0+x0xfx,ykdx      (1)

Since, x0=0

Then, the equation (1) becomes

yk+1=y0+0xfx,ykdx

steps
