I need to integrate the function d^2 y/d x^2=0
I know I need to begin by...
d^2 y/d x^2 =
d/dx * dy/dx =
d/dy * dy/dx * dy/dx
.... after that I am lost.
Cheme: It's effectively the same thing
y=(y2-y1)(x-x1)/(x2-x1) +y1 = Ax+b
where A= y2-y1/x2-x1 and B=((y2-y1)*x1/x2-x1) +y1
They gave you the solution in general form with gradient and everything from y-y1=m(x-x1) form..
All I did is say
y''(x)=0 --> y'(x)=A -->y(x)=Ax+B where A,B are constant..
