To determine

To find:

The recursive formulas for the Taylor method of order 2.for the differential equation y=cos(x+y),y(0)=π.

Answer to Problem 1E

Solution:

The recursive formulas for the Taylor method of order 2 is yn+1=yn+hcos(xn+yn)+h22sin(x+y)+sin(xn+yn)cos(xn+yn).

Explanation of Solution

Formula used:

The recursive formulas for Taylor method of order second is,

xn+1=xn+hyn+1=yn+hf(xn,yn)+h22f2(xn,yn)

Calculation:

Consider the differential equation.

y=cos(x+y) ……(1)

The differential equation is the function of x and y so,

y=f(x,y),y(x0)=y0 ……(2)

Compare equation (1) and equation (2).

f(x,y)=cos(x+y)x0=0yo=π

Differentiate the function f(x,y)=cos(x+y) with respect to x,

fx(x,y)=sin(x+y)

Differentiate the function f(x,y)=cos(x+y) with respect to x,

fy(x,y)=sin(x+y)

To calculate,

f2(x,y)=fx+fy(f(x,y)) ……(3)

Substitute sin(x+y) for fx, sin(x+y) for fy and cos(x+y) for f(x,y) in equation (3).

f2(x,y)=sin(x+y)+sin(x+y)cos(x+y)

Consider the recursive formulas for Taylor method of order second.

yn+1=yn+hf(xn,yn)+h22f2(xn,yn) ……(4).

Substitute cos(xn+yn) for f(xn,yn) and sin(x+y)+sin(x+y)cos(x+y) for f2(xn,yn) in equation (4).

yn+1=yn+hcos(xn+yn)+h22sin(x+y)+sin(xn+yn)cos(xn+yn)

Therefore, the recursive formulas for the Taylor method of order 2 is yn+1=yn+hcos(xn+yn)+h22sin(x+y)+sin(xn+yn)cos(xn+yn).

Conclusion:

Thus, the recursive formulas for the Taylor method of order 2 is yn+1=yn+hcos(xn+yn)+h22sin(x+y)+sin(xn+yn)cos(xn+yn).
