True and False with explanation
1.Eqn y"-2xy'+x²y=e^(x²/2) and y"+y=1 have same normal form.
2.Equation
cos(x+y)p +sin(x+y)q =z²+z
is a quasi-linear equation.
3. Every solution of the ordinary differential equation (D²+1)²y=0 is bounded on
[0, infinity[.
4.For the IVP, dy/dx=f(x,y),y(x0)=y0 the continuity of f(x,y) and df/dx Guarantees unique solution of the problem
